RMS and monitor speakers

I have a 54" plasma and a blu ray player. Need a little help in choosing the right recievers.

I have narrowed it down to the Monitor 60 or 70 and the suggested center, sub and rears.

Looking at the deals and I noticed a post saying of you get the monitor 70, they do need 150+ Watts RMS power to sound good.

Does this mean that the normal $400 range recievers like the Onkyo 507 will not suffice since it only puts out 80 watts x 5?

Thanks

P.S: If anyone can recommend a great $400 range reciever that would work for me that would be awesome!

    Here is a good artical about "RMS" power.

    http://sound.westhost.com/power.htm

    I always say the more power the better. Most AVR's or recievers power output do not represent the actual power they can produce. It is much less than what is stated.

    Will it drive your speakers? Most likely will be fine unless you like really loud music or play a move at concert levels. Your AVR does not have pre amp outs so you cannot hook a seperate amp up to it. So unless you go with a new AVR or AV Processer you will not be able to put a bigger amp on to give the speakers the power they can handle.

    Very informative link tuffman gave you there devilish.

    Another thing to remember, these AVR's you see online/at stores are a bit overrated in terms of power. Won't go into specifics seeing as you already read why in the article above.

    Just keep in mind though that if you listen to music/HT loud and don't have the power to drive your speakers, you're sure to kill your speakers due to distortion. Speakers are way more prone to damage from being underpowered as opposed to overpowered. Before you can push a speaker to it's limits.....the output should be a bit too much for your ears to handle so you shouldn't really be able to blow a pair of speakers by overpowering them. Driving them at high levels and making them distort because they're being underpowered will drive the speakers nuts and they'll ultimately croak.

    Is there a recommended reasonable ~200 amp that can be added to a different reciever?

    do you really need a amp if most of the sound is for tv and movies?

    How much do you want to spend? The Onkyo can power those speakers to reasonable levels because they are very efficient. But they would benefit from more power.

    If you can I'd step up to an Onkyo that had at least 130W/channel--most 800 series before the 806 can actually put out that wattage for all 5 channels continuous...at 8 ohms. They also weigh more than 50 pounds as a result?

    They have pre-outs so you can add a power amp for even more power. All this will raise your budget thought!!

    Lots of power amps available but you need pre-outs on your AVR to hook those into...

    Rotel, Parasound, Carver, Adcom, Nad...ta da, ta da, ta da...there are quite a few of these...look on www.audiogon.com for something in your price range.

    You can survive without a power amp! And I'd look into a Harman Kardon AVR 200 series....whatever the current model is....this will give you pre-outs for future power amps and other features plus a bit more REAL power than the entry level Onkyo.

    Your other option would be to go with an Onkyo 705/6 if you can find one in that price range, which may be difficult.

    The Yamaha RX-V665 seems to match what I need also although a bit pricey at the moment. My specific needs are:

    Can decode the latest technologies
    Video upconversion to 1080p
    Dual zone to power my outdoor speakers
    HDMI pass through of audio/video to reduce wire clutter
    7.1 for expanding to 7 speakers from the initial 5.

    It does have a pre-out at the back, so i guess at some point i can add a power amp.

    Below is the back of the RX-V665

    Can you recommend a reasonably priced (2-300?) range power amp that will take the 4 inputs and how explain how the connection would work? Its not quite clear to me looking at the various ones :(
