Voyager GAN 350
350wpc Balanced Power Amplifier

Above is a rendering

Our new LSA 350 watts/ch power amplifier, Voyager GAN 350, is now shipping. This fully balanced amplifier is a breakthrough product featuring a GAN (Gallium Nitride) FET Output Power Stage as found in products selling for many times our $3,000.00 price. This is a very sophisticated design and not just a Class D amp with GAN FET's. The current competition sells for $32,000.00, $18,500.00, $15,000.00 and $7500.00 with 80 watts. Our GAN Output Power Stage provides even better Audio performance through the reduced THD+N and IMD that is only afforded by the newest in eGaN FET Output Device technology.  Both of these enhancements are prohibitive with the legacy Silicon FET technology due to both the inherent limitations of the processes, and the resulting sacrifices in the desired efficiency of the system solutions.  These better efficiencies allow for increased Audio bandwidth without the “out-of-band” noise that is typical of legacy Class D amplifiers. These performance differences, along with an even better EMI/EMC profile are the result of the ‘almost ideal’ switching waveform that is achievable with this new eGaN FET technology.  The much faster switching times, the lack of ‘overshoots’ and ‘ringing’, along with the much reduced “Dead-Band” timing of the eGaN FET Output Stage allows for unmatched linearity across the entire Modulation range.  With the significant reduction in “ON” resistance and Gate capacitance of the eGaN FET, our amplifiers provide unmatched  Output Impedance and THD/IMD, resulting in the need for very low feedback – further reducing any issues caused by complex Output Speaker loads and Back-EMF from the transducers.  This means you get a greater depth of field, blacker blacks and greater transparency than standard ICE or Hypex Class D type amps.


This technology fixes all the issues that Class D amps have historically displayed.
Get up to $1,200.00 or more in trade for any working amp towards this new technology.

DPH-1 preamplifier/DAC/headphone amp

Intro sale $799.00
Now shipping

 In the new Stereotimes review they sum with:
"The Discovery LSA DPH-1 Digital preamp/DAC/Headphone amplifier is an elegant unit. It was mad fun to listen to as a headphone amplifier and use it as a digital preamp with my amps and speakers. Its DAC section sounds fantastic for the DPH-1's price – and this is coming from a guy who owns and uses a PS Audio Stellar Gain Cell DAC daily as his main go-to preamplifier with DAC."
Read the entire review at:

In the first review in Tone audio they said:
"Add it all up and LSAs DPH-1 is a fantastic DAC/Headphone amp. If I didn’t spin records, I could easily live with it as my main two-channel preamp and build a great system around it featuring speakers. It ticks all the boxes – easy to use, reasonable price, and sounds fantastic. What else do you need?"

Discovery is our inexpensive line. It is designed for audiophiles on a budget to discover great sound at affordable Internet Direct pricing with no dealer profits. The DPH-1 is our Discovery line DAC with preamp and quality headphone amplifier. It can be used as an excellent DAC or as a preamp/DAC. It may be inexpensive but is competes at well above its cost. It is a hi value remote controlled digital preamplifier with 24 bit/192k DSD DAC and quality headphone amplifier. We use the exceptional AKM 4495 DAC that is sonically one of our favorites. It uses an AKM AK-4118 digital input receiver. It has both tube and solid state single ended outputs. It features 4 digital inputs. The volumne control is a rotary encoder as found in much more expensive products. If turned all the way up it acts as a DAC if run into your preamp or integrated amp. It can even be run as both a tube and solid state DAC by using two sets of interconnects and running into two inputs of your preamp. The tube buffer stage is based on an NOS General Electric 5670 tube. This is the type of high value product that Discovery is all about.  It uses an R-core power supply, audiophile grade caps from WIMA of Germany, Solen from France and Dale resistors from the USA as well as gold plated connectors. There is separate power supply rectification for the analog and digital circuitry The included remote control handles input select, volume up and down and mute.

Discovery Warp One
150 watts per channel stereo power amplifier

Intro price is $999.00 delivered


First amp above- better shots will be coming
Our new Discovery Warp One, 150wpc, stereo amp will be the sonic class leader at its price point. It outputs 250 watts at 4 ohms. Is is 2 ohm stable as well. It is the perfect mate to our DPH-1 preamp/DAC above.
The Design is finished and we will ship in late July 2021.

The Warp-1 amp utilizes the class-leading Texas Instruments TPA3255 "Purepath" Class D amp Reference Design as our initial inspiration, but with extreme care in the layout design and choice of high performance componentry to ensure that the amp operates at its true potential. 
The state of the art layout was made using double planes stitched together with thousands of vias wherever an ultra-low impedance path was needed.  We do this to ensure extraordinary signal transfer which gives you ALL The Music and Dynamic Contrasts.
Attention was paid to keep current loop areas as small as possible. Power input paths were kept as short as possible as well.  The signal integrity is our primary focus here. Paying attention to these parameters yields phenomenal low noise for Blacker Blacks and Deep Soundstage that will amaze.

The ground paths were designed with a star hub topology (note that the power entry jack is in the middle of the board).  Ultra-high current low distortion CoilCraft flat copper wire SER shielded inductors for the output filter provide unfettered current flow while ensuring the minimum in distortion.  These are techniques found in Amplifiers at 5 x the price.
The PCB is an extra thick 2mm FR4 with 2oz (70um thick) copper traces and electroless nickel immersion gold (ENIG) finish.  All of these finer points add up to a sum that is greater than its parts, thereby yielding a Class D amp that sounds dynamic, engaging, natural, and non-fatiguing… so you therefore get a product that performs at many times it’s price --- but most importantly honors the Musical Event in a very real way.
The Class D amplifier is just the core, and it must be supported by a state of the art low-noise power supply and buffer preamp, both of which are custom made for Warp-1.  An oversized 600w switch mode power supply provides the amplifier with an abundance of power on-tap without a hint of hesitation.  Bass Slam will delight you track after track.
The Warp-1 has a custom made signal input buffer that accepts either balanced (XLR/TRS) or single ended (RCA) sources and utilizes our choice for best results --- the superb sounding state of the art Texas Instruments OPA1656 operational amplifiers for signal conversion and amplification.  The buffer has a DIP switch that allows selectable gains to match any source.  The gain on the input buffer can be selected from 0dB, 6dB, 14dB, and 20dB.  The TPA3255 amp has an intrinsic 22dB of gain so the setting from the factory is 6dB for an overall 28dB gain.  For most systems this will be the perfect setting to ensure trouble free, low-noise operation.
Some applications may require lower gain so 0dB can be selected for overall 22dB of gain. The 14dB setting will give an overall 36dB of gain which might be useful when playing from a less powerful source – perhaps a Lower Gain Preamp.  We would prefer that the 20dB setting not be used as this is just too much gain for most applications.
These components and techniques combine together to yield an amplifier that has a performance in the rarified air of 130dB signal to noise ratio. Even without a source playing, the Warp-1 will be absolutely silent with the ear pressed to the speaker cone - you cannot tell the amp is turned on unless the LEDs were glowing.  This amp can be used in every type and sort of High Performance Audio System with spectacular results.

The Warp-1 amp redefines what an affordable Class D amp can sound like.
