Iam interested in this as well, especially in hearing from people who have done comparisons with the usual suspects from Esoteric and the like.
I have had it in my system for over two weeks. And before that - DP-78 and DP-500.
That was a part of mt "new CDP" quest. I have also tried the Krell 505, Naim CD555, EMM SE combo, MBL 1531 and ARC Ref CD-7.
I liked DP-700 and Ref CD 7 the best, although IN MY SYSTEM, which is all-ARC, CD-7 had a slight edge.
But you can't go wrong with DP-700, IMO. And its build quality is second to none in the biz - it actually reminds me of my neighbour's Bentley GT Speed.
I have hade the DP-700 a couple of months. It is a very good player, and one of the best at its price point from my point of view. It replaced Cary 306 SACD which sounds like a cheap product in comparison. The Dp-700 is much more refined, has a precise and deep soundstage, much more liquid and analog sound. I have also compared it in my own system against Burmester 001 and the latest Burmester 069 reference player (both 2008 models). I found the Dp700 slightly better than the similar priced 001, but far behind the lot more expensive 069. I use my Dp700 for SACDs only as I now have the Burmester 069 for ultimate redbook playback.
The DP-700 is the best player that they have produced. It is only beaten by their new 900-901 and the soon to be release DP-720. It is better than the DP800-801 however. What make them sound so special is that the sound more like vinyl than digital but without the hiss. Something i should point out though is as standared it does sound softer and warmer than the 800-801 and not so open or detailed. You MUST conect the digital out to the digital in using their HS-Link cable. This transforms the play to a whole new level. I think this is because of the clocking. Without the cable the clocking is generated in the dac with the cable it comes from the transports own deticated master clock. This maybe the same for all of their players, if you have a digital in and out HS-link on your player try it!!
