Acoustic Technologies speaker deal
Save 70%

 We have bought a closeout on the Acoustic Technologies Classic speaker. This $2450.00 pair of speakers was a 2-year design project. The company designer finished the speaker & the passed away suddenly. We have bought the inventory from the family.
The Classic speakers are optimized in both the frequency and time domains. Using a single wide band driver properly sized to allow for all sufficient musical cues, he introduced a new technology to coherently present lower frequency information produced by the driver. This new technology uses a proprietary cabinet design to acoustically amplify the lower frequencies produced by the driver much in the manner that musical instruments do. They use solid silver internal wiring with Cardas CCGGL gold plated binding posts.

These speakers are great with small power tube amps like out VT-70 as well as 300B amps and other smaller high quality tube & solid state amplifiers.

 Realistic 3D sound staging / No “sweet spot” / Small profile /Low power consumption

Type: Full range, single-driver loudspeaker       Driver: 3” w/ titanium cone
Crossover/Filter: None   Nominal Impedance: 8 Ohms  Rated Power 15 Watts-30 watts
Dimensions: 43.25"h x 6.25"w x 9.75"d    Net weight: 35 lbs. per speaker

"The LSA VT70 is the perfect amp at the perfect price, whether investigating high - performance audio for the first time, taking your first spin with a tube amplifier, or perhaps looking for a great second system.

Audio GD
Superb R2R DAC with great press

In the new review in headfi.guru they say:
"To say that the Audio-gd R2R-1 met all expectations would be an understatement, in terms of musicality, accuracy, soundstage, detail, timbre, noise floor, and resolution, it is one of the finest DACs I have heard."
"If I were starting out from scratch and needed to purchase a DAC and Headphone Amplifier combination, this would be my choice, not to belittle my current reference gear, which I love, the Audio-gd gear is just that good".

LSA Warp 1 amp deal
Our state of the art 150 watts/ch. power amp
Five great reviews out already

Our new Discovery Warp 1, 150wpc stereo amp is the sonic class leader at its price point. It outputs 250 watts at 4-ohms and is 2-ohm stable as well. We designed this amp to compete with some well-regarded $3000.00 competition and are incredibly happy with the results

Headphone.guru said: "The LSA Discovery Warp 1 Stereo Amp, simply put, is the best sounding Class-D amplifier I have ever heard. With its musicality, power, linearity, abyssal noise floor, exciting dynamic range, and excellent three dimensional soundstage it is one of the best if not the best, amplifiers in its price range full stop."  Gary Alan Barker – Editor, HiFiAudio.guru / Nov. 2021

Tone Audio said: “Consider my attitude changed. The LSA Warp One is a great amp, period. Class D has matured, and very well I might add. For $1,195, we’re definitely awarding this baby an Exceptional Value Award. Job well done.”

In the new StereoTimes review they say: "What the Warp 1 does for its mere $1199 is extraordinary, delivering weight and dynamics in a musically satisfying way that defies its price category." “The Warp 1 is as engaging as it is affordable, an amp that offers a surprising amount of air, ease, and musicality for extending listening enjoyment."

Great new review out
Easily the best conditioner at anywhere near this deal

The new EQUI=CORE 1000 is a 1000 watt, balanced line conditioner. It comes standard with 3 Hubbell style duplex outlets. The 1000 supports up to 6 products. It also offers surge protection in addition to sonics that typically sell for $2500.00 – $3000.00 from the competition. It uses our latest transformer with improved low noise technology. It comes with a standard power cord and we have great deals on upgraded cords with purchase of the 1000.
In the new Tone Audio review they say:
"Five to ten minutes in, you should be able to hear what you need to hear. With the Equi=Core in place, backgrounds become more silent, which equals more dynamics, better low-level resolution, and none of the complex overtones that you’re used to with stringed or wind instruments are corrupted."
"Again, Core Power gets the job done right and without requiring you to cancel your vacation plans. Highly recommended.
The Equi=Core 1000 will handle 90% of the audio systems out there as well as all video and headphone systems.

 Audio GE Teddy Speakers
Save 48%

At Underwood Hifi we are always looking to present high-quality products that we can offer to our customers at great Internet Direct prices. In Audio GE, we've found a small Lithuanian company that makes great speakers with no North American presence. We've listened to their new Teddy and were amazed at the value. Sonically, Teddy leans to the warmer side of neutral and is a great, less expensive alternative to Harbeth. It's designed for rooms up to 3500 cubic feet. 

Teddy looks and feels like a smaller speaker at only 37" high, but punches with a big speaker attitude. They are detailed, powerful and capable of delivering excellent dynamics. A 10” Scan-Speak woofer/midrange and 1" Scan-Speak silk dome tweeter are used, along with a downward-firing port, making Teddy small but mighty. Bass down to 33Hz is deep, musical and realistic.

"Add it all up and LSAs DPH-1 is a fantastic DAC/Headphone amp.

 Deep=Core sale
It makes all power conditioners better

The Deep Core 1800 is designed to not only provide clean, spur free power but it also allows the user to optimize the power delivery interface via a user adjustment Contour Control. The optimization of the power delivery interface can significantly affect sound quality as the power company is a major contributor to attributes such as poor noise floor and dynamic range of the system. The Deep Core 1800 can be used with almost any system providing optimized power for both source components and power amplifiers.
It will work as a stand alone device, in front of the Equi=Core 1800 or in front of any other power conditioner you may already own.
  The Deep Core 1800 should be connected in front of your power conditioner as it is the "final" word in preparing your AC for a good power conditioner. Its uniqueability to not only fully cleanse AC power sources of both DC, EMI and RFI noise, as well as to match your AC to your individual components, is unique among competing products.
