Audio-GD R2R Ladder DAC Magna Upgrade
This upgrade has been developed in conjunction with Art Speak who has 30 years of experience in this area . Because we have gained a lot of experience with the Mano streamer, we had certain ideas about how things could be improved and sound better. AND IT DOES!
Audio-GD - R8HE - Regenerative PSU Balanced R2R Ladder DAC
The R8 R-2R ladder DAC is well received in the market, therefore Audio-GD decided to build the superlative of this model: R8HE. All R2R DACS including the new R8HE benefit the improved user experience: All functions are available from front-panel. (Jumper-less device) Enjoy your music!
Audio-GD - HE1 Vacuum Valve Regenerative PSU Preamplifier
This tube preamplifier with Regenerative PSU design is unique! Its sound is pure not only because of the regenerative power supply but also due to its thought out design. The preamplifier is designed around vacuum valves, resistors and SOLEN film capacitors. That’s it! No concessions or compromises. Only the best is good enough.
Hifi Advice APRIL 2019 "I think that the R8 DAC is the star of the show, sounding very nearly as good as the Aqua Formula xHD DAC which given its low price is an amazing achievement. But don’t assume that the Master 1 preamp and Master 3 power amp are mere bystanders. This pre-power pair also offers extremely good value for money, delivering a combination of transparency, neutrality, and even-handedness that is normally impossible in this price class."

Holo Audio – Azure – Discrete 8 amp module headphone amplifier
Azure is just an amp. So by function, it’s nothing particularly special at first glance. Just an headphone amp + pre-amp. Right? However, the key for Azure is the full discrete amp modules. There are 8 of them inside the Azure. 4 channels to be a fully balanced amp. And each channel has 2 discrete amp, one for buffering and one to amplify. Jeff Zhu has put tremendous amounts of time to develop this amp and has researched a way to get more detail and natural sound from a discrete transistor based amplifier. This is more comparable to tube sound however with better detail retrieval.

Holo Audio Cyan - REVIEW (Hifi Advice)
The Cyan promises discrete multibit NOS sound at a very friendly price in a great looking package. While not all discrete multibit DACs are equal, the Cyan delivers all the pure, unfiltered sound that is expected from NOS DACs while managing to not impose any character on top, outside of an occasionally forward upper midrange. Cyan is a spritely and dynamic performer that relays all the excitement that is in the recordings. Full Story
