My Chord Hugo TT2 has definitely changed a bit over the past few weeks. I'm slower to attribute certain changes directly to it, only because I've switched power cords and personally it's hard to isolate all changes directly to one component (in my opinion) because you have other things to consider like IC's, PC's, source components, etc.
I was using the Triode Wire Labs Obessesion PC, but now I'm using the Synergistic Research Galileo UEF PC which I've only had for a few days. So most of my observations are based on the TWL Obsession PC. With that said the most dramatic change has been less edginess. In the beginning, it was very analytical sounding. It was rather disappointing to be totally honest because those are definitely not the characteristic of my amp or speakers . Some folks love that sound, I am no fan of it. However, after about 2 weeks or so running it continually on average for about 12+ hours/day per Ken and Brooks Berdan in L.A. (shout out to Ken) the sound is more fluid, almost liquid. The highs are more balanced and blended with the mids and bass. There's a certain ease now that sounds more natural whereas before it sounded a bit too artificial. I like the fact that it is very neutral. By neutral I mean it doesn't really have a strong house sound. It takes the source and improves it. I have a pretty decent CD player (Cambridge Audio Azur 851C) and I absolutely love the synergy. I like switching it between "Amp" mode and "DAC" mode where my Gryphon Diablo 300 Integrated Amp does it thing.
I've noticed that with the Gryphon (and the Hugo TT2 in DAC mode) the soundstage is broader and there's more air. It sounds like there's more depth and yet there's still nice articulation, nice detail, and slightly darker (or warmer) sound. But when I run the Hugo TT2 in "Amp" mode, the soundstage is a bit more focused and forward. The bass is more concentrated and the PRAT seem a touch better and the mids are clearer and better defined. But there is still this nice neutrality of sound that is inviting and not clinical sounding.
Let me add that I'm running my CD player through my Chord M-Scaler and then through my Chord Hugo TT2 into my Gryphon Diablo 300 Integrated amp.
All in all, I'm highly satisfied!
