Thanks for taking the time to write up your impressions Todd. It does sound like a damn good value. Is the Dynahi a pretty transparent amp? I don't know how that amp sounds, and it will be interesting to hear your thoughts on the D100 through your speaker amp or any other headamp you have access to. Also, have you tried the Dynahi with the APL Denon? I'd be curious to know how it compares even though the price range is different.
On another note, it has been said before but why do these manufacturers keep using the same names for DACs and amps? Stello, Neko, Channel Islands, Cambridge, Genesis, etc. all have D100s or DA100s and I am sure there are others.
