my reciever is 75x6, out of curosity, if i had a 200x6 amp, would there be any noticeable differences, for example my speakers can handle alot more watts then my reciever can give out so will it sound better trying to get a high volume out of the 200 then the 75 or same, i know it'd be easier on the 200 to give 50 watts then for the 75 to give 50 but it seems like when the volume gets high it has trouble, kinda hard to explain you just know it is, like my 100x5 reciever has bookshelves, and they go louder easier and in a sense clearer or atleast better then my floorstandings which beat the bookshelves in quality any day of the week, seems like my floorstandings have trouble earlier and at a lower volume then my speakers on my other reciever do. Im wonderin if it could just be me cause of how the bookshelves well...dont know how to describe that sound and the floorstandings have that fuller sound. I hear some people talk about there like recievers from like 70-100 watts a channel and there like "these things rock hard, i get noise complaints all the time" and mine couldnt do that if there life depended on it and i cant put them any louder cause it feels like they cant. You'd probably wonder why i wouldnt use the other reciever, its cause it's only got Pro Logic, its 5 channels and it turns off alot..which im not exactly sure why, the other day i managed to turn my reciever off for the first time while listening to music. I think a good example of how loud i actually turn it up is i can still hear myself talk at a normal volume when im like 5 feet away from the speakers. Is my reciever turning off cause my speakers cant take it or cause it cant take it, i can just tell im not gettin close to what my speakers can do its just one of those things yah can tell when you listen to it, kinda frustrating cause i dont know if im hurting my speakers, hurting my reciever, givin it crappy power,or just 50% deaf. I seem to be able to get the speakers alittle bit louder if i turn the bass down on the reciever cause the subs get worked when i listen to music like they usually start flabbin out by the end of Lux Aeterna. Music is loudest in 6ch stereo but it's kind of annoying how the rear has a different kind of sound then the front and how i usually have my bass turned up alittle bit cause at 0 there's nothing there. Another huge thing i've been wondering about is my volume goes from 0 to 99, 0 being loudest and the loudest i've had music is like 22, would 0 be 75 watts? i hope not cause my speakers would probably start to distort at 15 by my guess, and after 22 i have to start turning the bass down so i dont blow them, i keep my bass at +10 until i hit like 30 then i'll move it down to +6 or +4 depending on what song, and if i would dare go below 22 i would put it to 0 or lower and it wouldnt sound good but not in a distortion kind of way, in another way. Most frustrating thing is i like to listen to music loud and forceful and i know im not tryin to get it ridiculously loud andddd im gettin a new amp soon but that still leaves my questions, for one i'd expect more out of a floorstanding speaker of the AS-F2's......calibur, i dont know how much bass im supposed to expect from four 8" subs and two 5" and one 8" (6.1) but i know im a bass freak in serious need of a sub.
