I am about to buy a surround receiver/amp and the choice is tough! Denon AVR2105 vs Yamaha DSPAX750SE More or less the same price but I am wondering if anybody HEARD the difference? Yamaha is 10W more powerful but Denon has a Tuner. also Denon seems to be a more award winner. I will be using it equally for Movies and Music. I listened to both of them last week in Belgium (Yamaha was cheaper there) and unlike what everybody says, Denon sounded better with music!? Like everyone else I enjoy the deep bass sound and I understand that Denon 2105 has been upgraded in this respect against 1905 but mainly the hi freqs are more important for me. Could you please share your views if you have experienced both. Also I have considered paying and extra £200 and getting YAMAHA RXV1500RDS because it is THX certified, is it really worth the money?? Many thanks Alp p.s. I have asked similar questions in another thread - a new thread would be better I thought.
