More power "better"


I am currently running a pair of Proac Response 1.5's with Classe 5 pre/70 power. They seem to play well and sound good, but I was told that more power would "open them up" and provide more control. I am also wondering at how much power is reasonable and not wasted. I would like to find some older Classe amps with more output but I am also wondering if an amplifier running "pure"class A would sound more powerfull. For example Krell KSA50s as compared to my Classe 70. Tubes also come to mind, but I think that new solid state is damn close if not better(certainly more reliable).If I were to go tube, I'd probably look at VTL MB125's (can't afford the big stuff). Any suggestions would be greatly appreciated esp. by those who currently own Proac.

hi alun,

i tink class-a amps *do* sound more powerful than comparably-rated non-class-a amps - prolly because they put out more current. the proacs would definitely like more power, tho what ya got should be sufficient in a smaller room.

the least expensive way for you to increase the power would be to get another matching classe amp & bi-wire - put the biggest amp on the mid-woofs of the proac; or if ya got another classe 70, ewe could try biamping vertically.

proac uses the audio research ls-16 & ls-25 preamp w/the a-r 100.2 amps, fwiw....

ps - i have an electrocompaniet aw100 amp f/s on audiogon - class-a, 100wpc into 8 ohms, 190 into 4 ohm, >80amps current output... :>)
