Funny you should ask that.......that is the combo I switched from! The Bypass mode sounds every bit as good as the Parasound. In fact, the digital input isnt bad either, a little edgier than my Adcom GCD600 CD player, but the DAC's on that puppy are really superb, and have shown up a few higher priced units. One thing Adcom truly got right.
You read about people complaining about the ergonomics of the 950, coming from the Parasound duo, you wont thing so at all.
DD is at least as good, DPLII blows away the THX mode of the Parasound. I am very happy with this unit. Oh, and the video switching is superior to the Parasound also, clearer picture, with less noise.
