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."

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.

Voyager GAN 200 Balanced Power Amplifier
$3,000.00


Our new LSA 200 watts/ch power amplifier, Voyager GAN 200, will ship by the end of June 2021. 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. 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 “Open-Loop” 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.
