Yes, I have it and am really impressed. IMO, It easily competes with any player in its price range. In particular, the redbook performance is astonishing. I find the bass extension and low end to be better than most players. The dynamics and sound staging are excellent with lots of detail. The highs are crisp and clean without being bright. The noise floor is very low. Imaging is accurate. I have preferred the Underwood Denon on redbook to several other more expensive players I've had in my system, i.e. Audio Aero Capitole MKII, Burmester 001, Sim Audio Moon Eclipse, and Cary 306/200. I'm not as impressed with the component video perfomance although I have not taken advantage of the activated DVI. I'm sure that will throw it over the top! I love its performance with DTS surround sound 5.1 recording. Obviously, that means movie soundtracks are top notch! Its the best I've heard. SACD is very good depending on the recording (!). I have not tried the DVD-A. I have also not taken advantage of the SACD surround aspects.
I would conclude that if you are looking for an excellent all around universal player with an emphasis on redbook 2- channel audio, this is the one to get and price wise, compared to the Linn, the Esoteric and the Goldmund, its a steal!
