I've got an Accuphase DP500 hooked to a Plinius 9200 integrated. Recently out of curiosity I bypassed the preamp section of the 9200 and connected the DP500 direct to the power amp section. I thought the sound would take a dive given the built-in freebie volume control on the Accuphase may be inferior compared to the 9200's preamp. Well the result was quite positive, I would not necessarily say better as the presentation is a little different, but definitely not sonically inferior.
To Accuphase CDP owners I was wondering if you are running it straight to a power amp or do you prefer to use a preamp and if yes why?
