Wow, just got the Uptone Regen, hooked it up via Mobo USB from my PC JRiver Windows 7 (no optimization) with a Supra cable to the Regen and my Black Dragon micro from the Regen to the Hugo HD (will test the adaptors direct). Big difference I am hearing, bass is far more noticeable, louder but defined. I am hearing things in the low range that I never heard before. I used to get some sibilance issues from my PC and it would fatigue me over time. Now that is all gone. I notice I have to turn up the volume more now, blacker background. If USB PC audio can sound this good with the Hugo, looking forward to more optimization of my digital chain. Count me a believer now. Bits are bits but electricity can be the damnation.
On further listening, with the Regen in the chain, there is a far better balance between lows (much more pronounced), mids (brought forward), highs (as is, less overwhelming). All makes for a very nice balance. Right now just playing a lot of familiar pop wave. Will try out other genres as the night comes.
