Best one box CDP, Got it short listed to Four

i would also add a marantz to the list.

i havent heard better redbook playback on any cdp to date plus it has sacd.

I love the EMC-1 and have one. Plus I just purchased a Resolution Audio Opus 21 CD player to replace a Marantz SA-14 SACD player, which wasn't all that great on redbook. The Opus 21 is a very dynamic CD player and should be great with rock and pop and jazz. Musical instruments sound natural too on the Opus 21 (and on the EMC-1).

It's not a one box CDP as the power supply and display are separated from the transport/dac (as opposed to most 2 box players which separate the transport and DAC), but the Resolution Opus 21 should be added to your list above. Its less expensive new than any of the players you've mentioned and in the same league as all of them. See www.resolutionaudio.com. Also, the size is only about 9 inches wide, so you could potentially fit both on one shelf.

Good luck in your search.

Of your short list I would pick the Accuphase DP-75V.

Sonics aside, the Accuphase has the best build quality of any of the players on your list. I have owned Accuphase players exclusively for seven years now (65, 75, 75V) and have never experienced a problem with any of them. I say this because owners of Accuphase tend to take build quality for granted. But after reading comments on Audio Aero and Philips, I believe this issue should be an important factor in your decision.
