Nice review Spookyfoot I was wondering what happened with your new toy. Interesting. Also interesting you have the Ygdrassil. I was thinking about that. Have the Teac UD501 which is pretty good but I dont hear much difference between the DAC and straight out of my Marantz CD6004 or Oppo 103. Your take on the 2100 vs 2000 pretty much agrees with my ears. I love mine. My local Hifi dealer still refuses to acknowledge the line. "I cant sell Yamaha". Heaven forbid, that's just wrong compared to the $3000 digital coax he sells. How about the phono? Are you using it? They upped the phono IMO.
