I'm considering the D1100, the plan would be to use it as the preamp instead of a c47 through the men220. I have a couple concerns though before pulling the trigger: a) Would the men220 actually reduce the audio quality coming out of the D1100? Would I not notice an improvement over the C47? When playing vinyl I thought the music lost a little magic, but the gains for digital in my funky room made the MEN220 worth it, and i can do without vinyl in this system. b) Would it sound better than a C47 + MDA1000? I have an MDA1000 in storage (upcoming move), which when paired with the C47 it sounded better than the C47 alone, which sounded fuller than the MDA1000 alone. I'm splitting hairs here. c) The MQA format. It seems a tad early to get hung up on the D1100 not supporting the extra folds through hardware, but it is a talking point. I do listen to a LOT of Tidal, but strangely I just heard of MQA yesterday. I always listened to Tidal through Audirvana and haven't had upgraditis in awhile, so I missed the buzz.
