    It depends on how big the room is.
    I have a Sony 5.1, 100W/ch and sometimes I turn it very high, but at some point it just feels like a loud noise thanks to the smallish speakers. I know I could go louder with bigger speakers, but probably wouldn't hit the max.
    That being said 100W/ch is plenty for an average room IMHO.
    I know someone who has a 2x500 tube amp with nice big speakers and he can turn it up to the clipping level without making it sound too loud.

    I can't imagine you'd hear $600 worth of difference....but that's just a guess. I'd go with the 110W....but then again I can't ever imagine dropping $1100 on a receiver...... :yikes:

    Many years ago i picked up a crown DJ amp for my home speakers using the preout on my old receiver. was a 125 watt Pioneer, but from 1993. The PB1 was nice, under $500, but only 200 watts per ch at 8 ohms. just didn't feel that great. I took it back and for about $600 got the PB2 at 325 watts per ch at 8 ohms. What a world of difference less then $200 made. But in the retail world, onkyo, Marantz, sony, they had amps with less juice going for $1500. Of course we're talking about less of a jump here with these Yamahas, hence my concern. I can't reuse the Crown, its rack mount with internal fans, just wouldn't work out in my living room. Plus these speakers aren't rated that high, I’d probably torch them over time.

    You really can't over power a speaker unless your completely stupid about it. What happens far more often is underpowering a speaker blows it up.

    Sorry about the prior post it did something odd and it will not let me change it

    this is true and I think most people don't understand this.

    Again, how?
    Speakers get damaged when operating parameters (especially coil travel and thermal dissipation) exceed the design limit.
    Outputting 10W into a 100W speaker will not cause more damage than outputting 90W into the same speaker.

    I can't edit my post? OK, I guess I'll just add another....
    though I'm sure the term "underpowering" isn't technically correct (and we all know how CeeBee gets about that stuff) the basic idea is that buying a 100 watt amp and 550 watt speakers isn't a good idea even though it seems logical. You think "well if my amp does 100 Watts and my speakers can handle 550, there's NO WAY I can blow them up." The problem is when you start pushing your amp to it's ouput limits you start clipping and sending distorted signal to the speakers doing this for a extended period of time will wreck your tweeters.

    that's what I have always understood "underpowering speakers" to mean. And when I was first buying audio equipment I didn't understand it either and had to get a couple of speakers repaired under warranty. Now I try to buy speakers that are rated close to the peak performance rating of the amp / receiver and buy more amp than I think I need so I'm not needing to "turn it up to 11" to get the volume that I'm looking for.
