I've had my Regen 4 days now and my system volume has gone into unknown territory thanks to both the increased clarity and decreased listener fatigue. This is a must-have no-brainer product for anyone into PC audio regardless of how good you think our system audio quality might be. While the clarity gains are realized throughout the audio range, it's the mid-bass that clearly stands out.
But there are issues, mainly certain high end USB cables that can prevent your USB Dac from being recognised my the computer when the Regen is plugged into it. I happen to have 1 such USB cable in the Locus Design Nucleus USB cable. Fortunately for me, I plug my Regen into the computer and then run the Nucleus to my OffRamp 3 USB converter and I'm still getting kick butt results that better using a stock USB cable with the Regen plugged into the Off-Ramp. The Corning USB optical cable is another that has given some owners issues.
Once the Regen gets some much needed press, this product is really going to take off. I'm glad I got off the ground floor with mine, just in time for summer's crank it up sessions. It's reminding me of 12 years ago when my system was brand new,,, only better.
Cheers,
Robin
