Do we really need amplifiers with 100watts per channel?

[QUOTE="Hennie, post: 1882, member: 20"] Chip, Schematics you can look at: QSC RMX 1450, ordinary class B (Behringer EP1500 is based on this): http://www.qscaudio.com/support/library/schems/rmx1450.zip QSC RMX 2450, Class H, otherwise similar to RMX 1450 (Behringer EP2500 is based on this): http://www.qscaudio.com/support/library/schems/rmx2450.zip Timber, These amps have small reservoir caps for their output rating, I think thats what Chip meant. The power output increase into lower impedance loads will be less compared to amps with stiffer power supplies. I dont expect PSU noise rejection to be particularly good with these amps. Also note the lack of a centre tapped supply. The protection circuitry is better than the nastiest consumer amps, but not up to the standard of the better ones. [/QUOTE]
