its a good DAC because of the pelnty of choises for modifiacation .....as a DAC ....because the headphone out does not use the tube part ...its SS only .....whatever tube you put in it wont cange the sound is youa re using it from "headphone out" ...tube only comes in to pcutre if you use the line out from the back (RCA)
also there are 2 places to put the opamp ( one for amp and one for DAC)
DAC od D1 ...plenty of choises ( tube rolling and diff Opamp choises ) ....v/s ....headpone amp D1 ( only opamp modification) (also i have read the HDAM sun helps only if used in the DAC part not the amp part ....may be wrong though as i dont have first hand experience)
did you Import the Hdam and w396a ...from where
And HM are not just for the AKG ...bassically they are meant for portable use ...( AKGs are anyyhing but portable).
