could use some help w/amp decision.

FYI
Speaking of switching, what do you think a class A/B amp does? It switches from Class A at low power to Class B at higher power. A digital "switching" amp like the rotel is switching all of the time. The output transistors are eigher ON or OFF and nothing in between. Any of the amps listed should work great for your application, but compared to Class A/B and G, digital switching amps are the newer and less proven design topology.

Class AB doesn't mean the amp switches between Class A and Class B. It might have been named that way because the amplifier behaves somewhere between Class A and Class B. It is also true that when the signal is small enough it behaves like class A but the circuitry itself is not class A. So it is not really switching between two modes. It is true that class D amps switch all the time but that's transistor switching, it is not the same as an amp that operates in Class AB mode and then switch over to Class G within 2 microseconds on demand. 'Transistor switching' is not the same as 'operating mode' switching. The full time class G amp that you talked about would not have the switching (mode) delay. Anyway, I never meant to say Outlaw's claimed 2 microseconds delay is audible. I only said it is one more thing that can potentially go wrong.

I hope this is at lease remotely on topic. For those interested, the following links to a description of different classifications of amplifer designs in simple ways that one doesn't need to take an EE course to understand.

Now back to the original postI've been looking at audiogon (shouldnt of)but the are a cpl of bel canto's specifically the evo200.2,s300 and the evo2 gen2.These would fit my price range.What do you guys think in comparison with the rotel rb1072.Unfortunately there just isnt any reviews by users or otherwise on the rotel for me to look into.I realize this may be loaded but i'm just trying to get whats best and learn at the same time.

Thanks for the link Peng, I have book marked it for later reading. Rice thanks for your "real life at home" experience with the mono blocks.

System Audio: SA-1750 Amp

thanks,but it's too big.I'd actually like to stick between the 2 i mentioned or similar.thanks again

Enrique, I currently owns a System Audio Home Theater Set up:

SA-1750 Front
SA-720 Center
SA-705 Rears
Yamaha Receiver RX-V2700
Yamaha DVD-S2700

I was wondering what amp did you finally bought to drive the SA speakers, since I tried Rotel RMB-1075 with a slightly improve is bass response that the Receiver. And the Rotel RMB - 1095 with a HUGE improve in bass respose. Have not try any of the Rotel class D Amps.

Thanks,
