People keep asking me for my thoughts on GS2, so here are my thoughts on Yggy GS2 vs BF2/64 on my rig (speaker setup) with my ears and my music.
VERY initial impressions (after 5 hours of warm-up):
Yggy GS2 is more holographic and definitely has more air around instruments. Soundstage a teeny bit less wide than BF2/64 -- at least for now as it is opening up with time. Yggy GS2 soundstage is definitely deeper front-to-back. Bass seems to have a bit more slam, but it may just be more controlled. Highs are definitely airy and more 'pure' sounding with no trace of etch or harshness. Definitely more texture and timbre, such that I could tell that what I thought was a metal glockenspiel was actually a Vibrahpone with wooden tone bars. I know this because I could actually hear the wood 'texture/tonality' underneath the note when struck. Never noticed that before on BF2/64. Live performances just sound more 'live'.
I'm hearing deeper into the music and picking out things I never knew was there in tunes I've heard many, many times. Sure, it's 2x more expensive than BF2/64, but is it 2x better sounding than BF2/64? Probably not. But it is better -- revealing nuances, air, texture and details I had not noticed. At this stage of the game, it's subtleties and nuances and how much you value them, I guess. Yggy GS2 is not humiliating BF2/64, it's just a bit better in many areas and all these areas matter to me. It's a lot of little things all adding up to make this a DAC that is worth keeping over the BF2/64 -- at least for me.
** Yggy's role will be as the DAC in my speaker setup, but I'll test it with headphones this weekend.
