if u guys remember from some time i was asking about upgrading my old KenWood amp to a new Yamaha amp,anyway i make the switch from sometime & here starts the sadness 1st specs: Old amp:KenWood KRF-V5030D (110wx5) dolbydigital only entry level amp bought it year 2000. New Amp:Yamaha RXV650.(payed 800USD for it coz it's very expensive here in my country Egypt) DVD:Sony DVP-NS305 Front speakers:Wharfedale Diamond 8.4 Center:Wharfedale Diamond8c Rears:bookshelf onkyo speakers (soon to be replaced with Diamond8.3) First i was happy with my Yammy & i though i heared more details than my old KenWood & also i was very very impressed by it's quality (my KenWood looks like **** next to the Yammy). but after sometime i tried to hook my old KenWood again to make a comparison. & the difference was NOTHING in stereo & on Movies while i bought the Yammy coz i always wished to have a Yamaha reciver & i know yamaha is the best in movie sounds how could it be the ****y ****y entry level KenWood match it??????!!!!!!!!!!! i though my room was the problem coz it's a little bit reflective & live room with lots of bare surfaces,so i tried moving the system to another part of my house that have more absorbant materials than my room,& i start listining to a CD & repeat a track i choose several times & still can't hear any difference. For movies i used BladeII DVD with the came with DTS:ES6.1,i watched a chapter on the KenWood in dolbyD5.1 & the same chapter on the Yammy on DolbyD5.1 & there was nothing!!!!!!!!!!!!!!!!!!!!! also to make things worse & that's why i really think now that am Tone Deft, while am using my Yammy & switching between DSP's in movies (Spectacle,Sci-Fi,Adventure) i don't notice any difference between them & i notice a very very small differnece in the surrounds between the DSP's & the Straight mode,while i could hear the difference in DSP's like (Jazz,Concert Hall ect..)in songs. Also i connected the pressence speakers which doesn't add anything at all to the sound. & to make things as bad as it can get i tried switching between DolbyD5.1 & DTS5.1 on BladeII DVD on my yammy (coz the KenWood doesn't have DTS) & as u may guess didn't hear any difference between DD & DTS only the DD was louder than the DTS track. Sorry guys for the long post but i really don't have anyone to discuss this things with him coz my friends & relatives all use PC multimedia speakers & doesn't really care about Audio or Hi-Fi or surrounds. So what do u think about it guys,could it be true as a dude over at AudioHolics told me before i buy my Yammy that i wouldn't get any sonic differnce between different Amps/Recivers?? He also told me that even if i got the yammy Z9 it wouldn't make a difference.
