New to the amp thing ...here is a question? If you have a 100 watt per channel reciever and you add a 200 watt power amp, do you have a total of 300 watts per channel or just 200?

    Are you driving a set of speakers with the receiver IN ADDITION to the set being driven by the power amp (assuming the amp is being fed the preamp out signal from the receiver)? If so, then I guess you could say you have a total of 300wpc, but it's not really the same as having a 300wpc power amp....

    No...if I added an amp using the pre-amp outs of my existing 100 watt per channel reciever...would I have 300 watts or just 200? All that I want to do is to amp my mains...which are SDA II's.

    I might be going about this all wrong....is it possible to have an amplifier coming out of the pre amp outs of my reciever? I am running a Yamaha rxv-800 and I need more power to my mains. Can I do this?

    If you're feeding the preamp outs from the receiver to a 200 wpc power amp, and it's driving your speakers, then you're running 200 wpc. The receiver is just acting as a preamp---essentially what it is doing is providing a means of attenuating or reducing the level of the line input, so that you have control over the volume.

    If your mains are particularily hungry for power.
    You can hook up just them to your amp, and the rest of your speakers to your receiver.

    If your asking if both the receivers amp and the additional amp can be hooked up to the same terminals on your speakers NO. If you are biamping with your receiver to one set of posts and you amp to another on your speakers YES. The mix won't sound to good IMO though. Some amps can be bridged together but a receiver and amp nope. This is what I have learnt over the years. If someone knows something new, I'm open.:)

    Ok ....I get it...then again ...I don't. I guess what I am trying to ask is this...I need more power, so how do I get it? Should I just chunk the rxv-800 and get seperates? Is there anything I can do to get more power to my mains and my center channel without having to get rid of my reciever?

    What speakers are you trying to drive? Better yet, how much money do you want to spend?

    There are lots of power amps designed for home theater applications with more than two channels. OutlawAudio makes a highly regarded (and very reasonably priced) five channel amp.

    More power is always good, but what is it exactly that makes you feel you need more power?...Are you hearing distortion at high volumes? I'd be kind of surprised if the RX-V800 has trouble driving just your center and surrounds.

    I am in the process of moving my equipment into a bigger dedicated room...so I thought that I would need more power because I have more space. I am driving Polk SDA II's for mains.

    well driving those SDA's, you are going to need more power. purchasing a 200wpc amp and hooking it up to reciever through the preouts is basically like having seperates. later you could upgrade to a stand alone pre/pro as that is all you would be using your rxv-800 as anyway. when using your pre-outs, you are by-passing the reciever's amplifier, and sending the signal to your 200 wpc amp. therefore you get 200wpc, or whatever the amp you hook up is rated at....

    I am having the same problem. I have RT800i's for fronts. but with my little 70wpc receiver. it's just not enough to really get the 800's to perform all that great. I love the 800's. but I know they would sound better if I could hook up an amp to the fronts. I'm happy with the other speakers, just not the mains. I've been looking at the Marantz mono blocks for the fronts. Or should I get a 5 channel amp for all except the sub or course? so many choices out there.

    i'm in the same boat dange boy. my 5x100W reciever just isn't cutting it. i need to upgrade to a pre/pro or a reciever with pre-outs before i can get the proper amplification to my 800's though. the marantz monoblocks are amazing, i've auditioned these on def tech's. effortless... they are beautiful. if you have the means to go with these, go for it! you'll be happy...:D
