Hi All So I am nearly ready to pull the trigger on a Pair of CM 10 S2's, I took my Rotel RMB-1575 and my NAD M51 to Sevenoaks in Sheffield and spent a good 3 hours listening to them with my amp. They sounded amazing, and I commented to the sales guy that in terms of sound quality I would put them 100 % better sounding then my Kef q500's, obviously they are 3 and a half times the price and should sound that good, but their was a comment that was made by the sales man that has got me thinking, he said that he has the cm10's at home and a nad M51, but that he had the top end Parasound amp (i didnt get the model number) at home that was about £8000, he said that this was the first time he had heard the Class D rotel amps and that in his opinion my amp was just as good as his parasound and said that his amp couldn't go as loud as mine could, but we both agreed at that level the highs were starting to sound a little hard. He said the Parasound had a slightly softer sound but that he felt it was maybe 2 - 3 % better than the rotel. Now comes my question. So I was told that with my amp is not revealing enough to power the 800 series speakers, specifically 804 and 803 Diamonds but what do you guys think? Unfortunately Sevenoaks don't have the 800 series speakers so I can't audition, what's your guys view? are the 804's worth nearly double the price of the CM10 and could my amp power them?
