coax->lyr (6N23P) -> bifrost -> LCD-2 r1
Just to chime in with my thoughts, I've had the Bifrost about 4 days now and so far I'm really enjoying it. Mind you I'm coming from a D10 coupled to my Lyr so take my impressions with a grain of salt, but the Bifrost really is night and day in comparison across the board. The thing that especially jumps out to me is the imaging; everything has such a 3 dimensional and voluminous sound to it that I've never been able to get out of the other dacs I've owned. I had even all but decided to move on from the LCD-2s to the HD800 because I thought they were never going to let me hear into the music to the extent I wanted, but that idea is pretty much out the window now, and I've been having a lot of fun revisiting all my music with the LCD's. Even some of the poorly recorded music I have is showing some new life. On top of that, the soundstage is much more fleshed out but only a bit wider, although in all fairness my LCD-2s have never really shined in that department. I really get the feeling I'm listening to an actual room/stage rather than a wall of sound. Detail wise the bifrost is pretty big step up and I'm hearing several nuances I've never caught before, even in some of my favorite songs. It also feels like extension on both ends has been upped a notch or two. Tonally what I'm hearing sounds pretty neutral, maybe slightly warmer but I don't really get the impression it's coloring the music to any significant degree. So far I'm having trouble coming up with anything to complain about. There were a few hihats and drum beats that sounded a little thin when I first started listening, but my ears might have just been a little wonky as I haven't been able to find them again. Build quality is of course simple and solid.
I don't have a high end reference to compare to against higher price points, so take everything with a grain of salt, but I have to say I'm quite pleased with the sizeable bump in clarity and detail. I've always been a pretty underwhelmed with my past DAC upgrades (HDP, D10), so it's nice to finally have something that really adds to my rig.
