Best one box CDP, Got it short listed to Four

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.

I would also add Marantz to the list...the SA-14. I have been very involved in audio for 40 years, and this unit is one of the biggest surprises that I have come by. It is an unbelievable steal on the used market.

I have owned Levinson 390S and Wadia 850 and Accuphase 65. Any of these should be considered. They aree all quite nice with the Levinson at the top of this list

Go listen to them...the players themselves that is, not the subjective comments from people who have not heard all of them.
