This is something that i've been thinking about for a while now. Is there a big difference in surround sound quality between a budget DVD player and a high-end one? I have read endless posts on the CD playback of DVD players, but not a great deal on surround sound quality comparisons. For example, there has been a lot said about budget DVD players such as the Tosh 340 and the Pion 575, in terms of picture quality. But not a lot is said about their sound quality with DVDs. I have tried a fair few budget DVD players which have all been fairly similar to my ears. I have also had a ROKSAN Kandy mkIII, which is known for its great sound quality. Yes, the ROKSAN was excellent with CD playback (for a DVD player), but in terms of surround sound quality, i'd say my current Marantz DV4500 is at least as good as, if not better! Lets not forget the ROKSAN retails at £650! - over 3 times the Marantz. I am using a Yamaha 640SE amp. Maybe this is the reason I didnt notice a difference with the ROKSAN. Maybe if I had a mid-high end amp, I would notice a difference between the DVD players mentioned. Can anyone clear this up?
