DAC-2DSD SE
Now with Femto clock and even lower jitter

     The new Wyred 4 Sound DAC-2DSD SE ($2549.00), a Special Edition version of the highly acclaimed DAC-2 is now shipping. During development of the original DAC-2 Wyred recognized that digital streaming technology would move very quickly. They created a modular circuit design which would permit future upgrades as the industry progressed, and they can now deliver that promise!

   Upgrades from the DAC-2 to the SE are available for $1300.00. Call to discuss
 
     The newly refined DAC-2DSD SE incorporates many upgrades throughout the digital, analog and power supply circuits. In addition to the enhanced sonic performance, the new SE version has extended its USB support to include, driverless (Mac/Linux), 32 bit 384kHz PCM, as well as DSD streaming.

The new Femto clock lowers jitter to 1/7th of what the original SE had.

     The 9018 ESS Sabre DAC remains the heart of the DAC-2SE which is still widely regarded as the number one D-A converter in the industry. The ESS DAC was originally selected for use in the DAC-2 for numerous reasons, one of which is the capability to process DSD signals which it can now decode. The I²S DSD format offers a jitter free solution to transmitting digital data from our cutting edge USB interface to the Sabre chip. Newly implemented technology and hardware now takes full advantage of this remarkable feature. Either DSD64 or DSD128 files can be flawlessly streamed in conjunction with standard PCM files. The DAC-2SE instantly detects the native DSD data and routes the signal to the appropriate internal processors resulting in unparalleled sonic performance. It’s time to begin expanding your DSD music collection!
    
Another bonus of the special edition DAC-2DSD SE is the galvanically isolated I²S USB interface which guarantees zero opportunity for computer noise to interfere with the quality of the audio signal. Setup with your source via USB is simple because the DAC-2DSD SE is driverless for Linux, Mac OSX 10.6-10.8, and supports Integer mode protocol.
 
 Wyred upgraded many key components throughout the entire audio circuit starting with the main fuse at the power inlet. The Furutech rhodium plated, ceramic fuse has proven to be an excellent complement to the upgraded power supply of the DAC-2SE. Further filtering is addressed with low loss - ultra fast recovery Shottkey diodes and a series of premium grade inductors that assist to stabilize the current as it enters the power supply. Power is then filtered through a series of custom low ESR capacitors after which it is regulated by newly designed discrete regulators. The Wyred proprietary regulator design is 100+ times quieter and faster than the stock regulator of the original DAC2! The start of the analog signal receives strategic treatment with custom made naked Vishay Z-Foil resistors in 20 locations. Putting numbers on it, the stock Dale resistors offer 1% tolerance and +/-100ppm/°C temperature coefficient where the new resistors are 0.1% and +/-0.5ppm/°C respectively. This new DAC-2SE has superior sonics and again places this new DAC 2SE against DAC's selling for 2-3 times its price.

mAmp 
$895.00 each

The new Wyred 4 Sound mPre ($1095.00) and mAmp ($895.00 each) are the newest models from Wyred 4 Sound. These two new products finish the Mini series along with the integrated amp shown below. The mAmp power amp is a 250 watt mono amplifier into 8 ohms and 430 watts into 4 ohms. It has no problem driving 2 ohm loads. The mAmp is a fully balanced design with the Wyred 4 Sound new balanced FET input buffer to add a tube-like warmth. There is also a 12v trigger for turn on/off.



mPre
$1095.00

The new Wyred 4 Sound mPRE is a fully balanced remote controlled preamplifier/DAC in one small box. It offers much of the performance of the exceptional STP/SE preamp and DAC2 in one box at a very affordable $1095.00.
The fully balanced, dual mono, dual differential circuit design uses over 80 FET's which are paralleled up for much lower noise and increased current output. Input and output stages have been incorporated to preserves sonic integrity throughout the circuit.
The m-PRE has a built-in DAC with three inputs which includes toslink, coaxial and USB. All of which support 24 bit 192kHz streaming. The ESS Sabre DAC utilizes Hyperstream™ and Jitter Elimination Architecture rendering it immune to jitter. The USB interface is derived from the latest asynchronous XMOS design which is certified USB 2.0 High Speed and Audio Class 2.0 compliant. Incredibly low latency in conjunction with the asynchronous mode of communication and ultra precise clocks permits for an exceptionally high quality level of digital streaming.
The mPRE is equipped with 3 analog inputs and outputs. Two of the analog inputs are RCA and one can be configured as Home Theater bypass. The two RCA outputs are typical pre-outs and one set can be configured as a fixed out. Finishing it off is the XLR input and outputs which use high quality Neutrik connectors to couple the purely balanced circuit with any other components you may have. Single ended to balanced conversion comes at no extra charge and ensures that all outputs are active regardless of the input signal type.
The m-PRE also has a high quality headphone amp capable of driving headphones down to 16 ohms.


mInt

The $1,495 Wyred4Sound mINT (mini integrated amp) is a wonderful new 100wpc integrated amp with a fine DAC and headphone amp. We introduce the mINT at the Rocky Mountain Audio Fest where it did a superb job running our Emerald Physics system. We received the Best Reasonably Priced Soundat the show from The Absolute Sound. The mINT is a preamp, power amp, asynchronous DAC and headphone amp in a small high-performance package. It offers superb performance for the price and makes a great center section for a quality hifi system. Just add a pair of speakers and inexpensive CD player or computer as a source.

The mINT may be small but it is big in performance. The volume control is a trueresistive ladder which results in linear control, excellent channel matching and great sonic quality. Rather than passing the signal through a volume pot, the control is only used as a position reference. A soft ramp feature means that when powering the unit on/off or using the mute/un-mute, it increases/decreases the volume at a pleasant rate. The mINT has a 12V DC trigger in and out as well as an external mains voltage switch.

Two analog inputs (auxiliary 1 and 2) are side by side on the rear panel. An alternate function of Aux 2 is home theater bypass and is activated via a push switch on the back. The preamp output will work to run a powered subwoofer. In addition to the preamp out the mINT has a fixed tape out that will typically be used to send a signal to a recording device or feed a second system. An alternate function of the fixed out is a main-in feature that can be used with the preamp output to allow the insertion of a digital crossover or processor into the signal path. This feature can be selected by the “Fixed out/Main in” button located on the rear of the unit next to the HT Bypass selector.

Located top and center of the rear panel you will find three digital inputs, coax, optical and USB powered by an ESS Sabre DAC chip. The S/PDIF inputs will support 24/192 files and the asynchronous USB interface will support 24/96 hi resolution files from your computer. Each digital input can be connected to a different source and selected independently via the remote or input select buttons on the front.

A ¼” headphone jack is machined into the left had side of the front panel. When a headphone is plugged into the jack it will mute the speaker output (other than the fixed outputs) regardless of the input selected or volume level. The headphone amp is impressive and will even run hi-impedance phones. It uses independent power supplies for exceptionally low channel crosstalk, low noise and wide dynamic range that make for true high-fidelity headphone experience.

The mINT is dual mono and uses two independent new X-series ICEpower™ modules each with its own power supply. The new X-series has the best performance of any digital amp from ICEpower. The mINT puts out 100wpc into 8 ohms and 170 watts into 4 ohm loads. It will drive the majority of speakers on the market with ease. The mINT is made in the USA and comes with a 3-year factory warranty.

DAC's

The new DAC’s from Wyred bring world class performance to realistic price points.
  • DAC1 32-bit DAC with 9018 Sabre chip and 24/96K asynchronous USB input $995
  • DAC2 DSD Reference DAC/Preamp with 32/384K asynchronous USB input, preamplifier built in, home theater pass thru and I2S over HDMI input. $1595

Both the DAC1 ($999) and DAC2 DSD ($1595) use the ESS 9018 Sabre DAC. This DAC chip is considered by most to be the finest made. It is actually 8 DACs on one chip. Wyred uses 4 DACs per channel. The DAC2 review in the Feb 2011 Absolute Sound was a rave. They were shocked at how close the DAC2 at $1495 was to their $6600 reference DAC. The review in 6moons.com on the DAC2 was also a rave. They gave it a Blue Moon award and said: "The value assessment of this assignment has progressed to a predictable conclusion. Being so close in performance to an established $5,000 benchmark—the Weiss Minerva won UltraAudio's Select Component distinction and a Blue Moon award from us—and bundling greater functionality for just $1,500 doesn't, in this context, make Wyred's DAC2 an actual giant killer. It does very much make it a killer value in high-performance digital however." Read the entire review here.

The DAC2 DSD can be used as both preamp and DAC. The DAC1 is a DAC only. Both are fully balanced. The DAC2 DSD uses a 32bit/384k asynchronous USB input. The DAC1 uses a 24.96 asynchronous USB input. The DAC2 DSD also uses upgraded parts in comparison to the DAC1. Regulators and caps are improved. Both DACs are built around the state-of-the-art ESS 9018 Sabre DAC chip. This chip is an 8-channel DAC that is run dual mono double dual differential to output two balanced channels of audio with almost nonexistent jitter. The 9018 is considered by most to be the finest DAC chip made at any price. It uses 500kHz oversampling. The output stages use a 35-amp Schottky bridged rectified power supply and has 88,000uf of filter caps. In addition the DAC2 uses Wyred4Sound low ESR supercaps as used in their STP-SE preamp. This power supply is larger than many power amps. Both DACs use a fully balanced design with balanced and single-ended outputs. They both use an oversized toroidal transformer.

Upgrade your DAC2 to the DAC2 DSD for $495.00

Features common to both the DAC 1 and DAC 2DSD are:
  • ESS 9018 Sabre32 Reference DAC (32-bit DAC)

The DAC-1 and DAC2 are 32-bit multi input DACs that sets new standards in their price ranges. They are only sold Internet direct and would be priced double if we used dealers. 

The $399 Wyred4Sound µDAC is the perfect solution for digital streaming and CD player upgrading made simple. Whether it be for a second system or to begin digital streaming for the first time, the µDAC is a great solution. Although small, the µDAC can play with bigger competitors. There are two S/PDIF inputs which support 24/192 signals as well as an asynchronous USB input for computer streaming. Any of the inputs will provide the kind of performance expected from a price tag far higher. From Internet radio to high-res streaming, the µDAC will not miss a beat. The µDAC uses the very same USB technology used in the $1000 DAC-1! It even include an ESS Sabre DAC to take full advantage of the limited real-estate in this 3.5” x 3.5” chassis. the µDAC is made from machined aircraft-grade aluminum with the W4S logo as a lock light (lights up blue when the DAC is locked to a signal). The µDAC is very functional yet so simple. Power is fed directly through the USB buss when streaming from a computer. When using the S/PDIF inputs the USB cable is plugged into an outlet using the supplied adapter. Simplify and improve your digital streaming today!

SX mono amplifier
The SX mono amps are full mono designs in with 570wpc. The SX1000's double power into 4-ohm loads and are stable into 2 ohms. These amps use the same B&O ICEpower™ modules as other highly reviewed products from Bel Canto, Jeff Rowland, PS Audio and Red Dragon. Wyred4Sound engineers then adds their custom buffered input stage to add warmth and they also modify the modules with upgraded parts. Reviews have all been excellent and all refer to the amazing value and sonics these amps offer.

ST MKII series stereo power amplifiers from Wyred 4 Sound
  • ST-1000 MKII 460wpc dual mono stereo amplifier $1999
  • ST-500 MKII 250wpc dual mono stereo amplifier $1499
ST MKII stereo amps are full dual-mono designs in 250 and 460wpc versions. They are two mono amps in one chassis. They do lots more power into 4 ohms loads and are stable into 3 ohms. The only parts shared by the two channels are the box and power cord.

The new MKII series is smoother in the highs and has better upper midrange than the original ST500 and ST1000 models. Theya rew clearly more analog like with better musicality.

In the 1st review of the older ST-1000 Jerry in 10Audio.com says: "In Wyred4Sound's ST-1000 stereo amplifier we have a maturing technology that absolutely changes the performance-to-price expectation for solid-state amplifiers in the $2,000 to $10,000 price range. Read the entire review here.

John Potis in Positive Feedback reviewed the smaller ST-500 and summed up with: "...in some ways the Wyred4Sound is a groundbreaking accomplishment that'll bring a new level of power and sophistication to a budget conscious listening audience that could only dream of such performance before." Read the entire review here.

Both ST MKII series stereo amps are dual mono designs. The only common parts are the chassis itself and the power cord. Competitors from Bel Canto and Jeff Rowland sell amps for multiples of the cost of the Wyred4Sound models thru dealers.

Wyred4Sound takes these new upgraded B&O ICEpower™ amp modules and modifies them to sound even better. Modifications include extensive use of Dale resistors and Muse audiophile-grade capacitors as well as other upgraded parts. The Stereo ST MKII series also feature a 3rd generation custom buffered dual FET input stage designed by Bascom King. This very high-quality input stage has an input impedance of over 92k to work with all solid state and tube preamps. You will find all specifications listed below but it is worth noting that these amps have a distortion level below 0.02% and a damping factor of 2000 for tremendous woofer control.

Sonics are exceptional with superb low level resolution, exceptional transparency and tremendous bass detail and extension. All Wyred4Sound ST amps are made in the USA and come with a 3-year factory warranty.

Wyred4Sound STP/SE 

Remote controlled passive/active balanced preamplifier 

$1999

The STP/SE brings the same amazing performance for the dollar as the Wyred4Sound power amps that have received such great reviews. I waited over a year for this preamp. It was worth the wait. It is sold direct to the end user with no dealer profit margins. If we used dealers this would be a $4000 - $5000 preamplifier. Reviews have been superb and even compared the STP/SE to $10.000 tube preamps. Call me at 770-667-5633 to discuss.

Feel free to listen to any solid-state preamp and compare sonics as well as features to our STP/SE. I think you will be amazed by its value. The STP is a fully balanced passive design that has an active gain stage that is only used when the volume control is advanced far enough to need it. It has over 164,000uf of power smoothing capacitance. This is far more than most power amplifiers. It is available in both black and silver finishes. Most of the time you are listening to a fully balanced passive preamp run through a custom-designed fully discrete volume control using Dale resistors. The volume control is controlled from the front panel or remote control by an optical rotary encoder. If you're looking for the ultimate in transparency, in an unbelievably accurate preamp with superb dynamics and exceptional imaging then the STP/SE may be for you.

The feature set is amazing.
  • The preamp is fully balanced from input to output.
  • It has 2 sets of XLR balanced outputs as well as 2 sets of RCA single-ended outputs.
  • There are 3 sets of single-ended RCA inputs and 2 sets of balanced XLR inputs.
  • It has 12v triggers to activate the home theater pass thru that is customizable for any input.
  • There is a balance control
  • Absolute phase control
  • There is a customizable multichannel pass thru
  • Made in Atascadero, California
  • Three year factory warranty
  • Available in 120 volt US or 230 volt European versions
  • Available in black or Silver finish

The STP/SE is the giant killer preamp like the Wyred4Sound amps that have received review comments like: "The Wyred4Sound is a ground breaking accomplishment that'll bring a new level of power and sophistication to a budget conscious listening audience that could only dream of such performance before." See the entire review here.

Also, "the high-end is dead! Long live the high-end! A paradigm shift is upon us now. In the Wyred4Sound ST-1000 stereo amplifier, we have a maturing technology that absolutely changes the performance-to-price expectation for solid-state amplifiers in the $2,000 to $10,000 price range." See the entire review here.

The STP/SE preamp full feature set is as follows:
  • Vacuum Fluorescent Display (VFD)
  • Optical rotary encoder (volume knob)
  • Fully functional remote control
  • 12V DC Trigger input (to automatically activate HT Bypass mode)
  • 2- 12V DC Trigger outputs

  • Compact size (17”W x 4”H x 13”D)
  • 20 lbs.
  • Covered by a 3-year warranty
  • The STP/SE preamp is only $1995 + frt. 

Integrated amplifiers
  • STi-500 250wpc balanced remote integrated amplifier w/HT bypass $1999
  • STi-1000 570wpc balanced remote integrated amplifier w/HT bypass $2499.00
Combining a slightly scaled-down version of the STP preamp and the same proven ICEpower stereo amp modules used in the ST-500 & ST-1000 separate power amplifiers, the new Wyred4Sound integrated amps are true giant killers. Both offer balanced and single inputs as well as a home theater pass thru. They have balance and phase control on the remote controls. Compare these amps to others selling at multiples of their price as they offer superb value. The STi-500 is $1999 and offers 250wpc into 8 ohms (550 wpc into 4 ohms), the STi-1000 is $2499 and boosts output power to 570wpc (1,100wpc into 4 ohms).

Some review excerpts on Wyred4Sound integrateds: "...As for me, I know a great deal when I hear one. I’m buying this STI-500 and it will be staying put in my reference system for the foreseeable future. It’s been my pleasure to see and evaluate this well-built USA-made product that not only competes with but actually outperforms both imported and domestic products in and above its price range. Happy Listening!" - full review here.

"...The STI-500 is very green, extremely good sounding, built to last, and very convenient. I have failed to acknowledge how much I like the preamplifier section for its flexibility and convenience since it just does its job without drawing attention to itself. In truth this amplifier doesn't draw any attention to itself with anything other than its exceptional sound. If Class D amps like the STI-500 are the future, then the future is going to be wonderful..." - full reviewhere.

"...For years serious hifi has traditionally meant separates. Wyred4Sound has challenged that preconception with a no-compromise single box solution which gives little ground to any separate dynamic duo (and made this proposition temptingly affordable). This is a serious effort and in the right system the STI 1000 will perform with a vengeance that belies its size. Powerful, efficient, musical - separation anxiety? Perhaps it’s time the masses embraced integration." - full review here.

There are high performance multi channel amps are attract ice prices.

MC multi channel power amplifiers
The MC multi channel platform offers the ultimate flexibility. With anywhere from 1 to 7 channels and power levels of 250 or 570W (8 ohms), this amplifier design adapts to your stereo or multi-channel system. Because of the modular design, future upgrades are done with ease should you not need all 7 channels at the present time. Each channel is driven with an independent direct coupled balanced dual FET input buffer. Components of the highest quality are being used from the power supply caps to the critical resistors. Wima audio-grade, Nichicon Muse caps and Dale Rn55d copper leads non-magnetic resistors are standard. With the selection of the high-pass filter on the front right and left channels, you can easily bi-amp your speakers without the use of any external crossover. Should you not want the crossover on, you can turn it off with the push of a button. With balanced or unbalanced inputs you can easily select the input with another push button on the rear. Dual 15A IECs, internally connected with 10AWG wire, gives you the option to supply massive power to the amplifier and also allows the use of after-market power cables. Up to 7 sets of gold-plated binding posts are connected with pure silver paralleled with 99.9% OFC copper to deliver the music which we have all come to love.

In the August 2008 Ultimate AV review David Vaughn sums up his MC amp review with: "During my time with this amp I have been in audio heaven. When I review a product I usually look forward to placing my own equipment back in my rack but that wasn't the case here. After I reinstalled my Anthem, I instantly missed the Wyred4Sound, and I immediately put it on my short list of upgrades—it's that good." Read the entire review here.

Like all Wyred4Sound amps, the MC amplifiers have little to no heat, excellent imaging, extremely low noise, tight clean extended bass and throw a big 3D soundstage. Distortion is exceptionally low. Check the prices below. They are about half that of the competition or even less. With an infinite number of possible amp combinations almost anything is possible from 5 or 7 channel home theater to biamping or even triamping your speakers.

The small chassis Mini MC amplifiers are fully balanced 220 watts/ch multichannel power amps in 3, 5 or 7 channel versions. We can also supply these in 220/240 volt versions for international sales in countries without a distributor. The Mini MC is available in 3, 5 and 7 channels. The amp has balanced input and produces a robust 220 watts per channel into 8 ohms and 360 into 4 ohms with 430 watt peaks. The amplifier is a true multi-mono design, each channel completely independent from input to output. The only thing they share is the power cord and chassis.

There are separate inputs for balanced or unbalanced connections that are easily selected by a switch on the rear of the unit. The input stage was designed for optimum sonics maintaining fully differential operation from inputs to output. It also optimizes the input impedance for all sources so tube or solid state preamps can be used with this amp. The amplifier includes a trigger input and output, rear panel on off switch and a dimmable blue power indicator.

The Mini MC is based on one of the newest Icepower modules the ASX-125. The efficiency exceeds 90% in both amplifier and power supply sections, which secures cool operation and enhances product reliability. Combined with the low idle consumption, which is 5 to 10 times lower than in comparable Class AB amplifier assemblies, the ASX2 solutions are a responsible choice when caring for the environment.

Each amplifier channel has its own power supply to allow 220 watts in any configuration. All models produce 220 watts, at 8 ohms, into all channels simultaneously, and 360 watts into a 4 ohm load. There are 3, 5 or 7 mono amps in one chassis. The amps have the standard Wyred 4 Sound 3-year factory warranty and are made in their California factory. They are only sold Internet Direct and have no dealers to keep the cost down. Feel free to compare these amps to others selling for two times their price.
