More power or better quality power?


I use a 120 watt NAD integrated and a pair of Sonus Concerto Monitors (Home version), and a REL stadium III for the low end. I am researching new integrateds because my System sounds lifeless. My car system sounded much the same before I added a higher power (twice the wattage) and higher quality (3 times the price) amp. The difference was night and day. So I am wondering, do I need more power for my home system, or do I just need better quality power...or worse yet, BOTH! My room is pretty large (18 by 18 give or take, plus a high vaulted cieling). The system is tucked in a corner and i listen from about 8 feet away on axis. I listen to everything, but mostly rock. I was considering a 100 watt Primare that is on audiogon right now. I was going to go Plinius, but I think with warm speakers, and warm cables (cardas) That might be just too much warmth :)
Low level quality of sound is important because I do no live alone and don't want to need to crank it to get a good quality sound.

So, is bigger really better, or is it it the quality?

I agree with Phd (and Ralph, as well, given the simplicity of his circuit designs). I also agree with Sugarbrie that effort expended in trying different speaker placements, including crossing both in front and behind you may radically improve sound.
8 feet is fairly close, yet even a foot or two more of semi-nearfield listener position may allow the use of a lower power, high quality amp and lower average listening spl.Of course, I'm one of those whose high volume listening days are way over. Well-mated components do the lower volume thing in a very satisfying manner and gain much greater acceptance from those sharing your domicile.
For what it's worth, I had an NAD C370 which I liked, changed to a Consonnance 8200 which I felt was a step up, but a little brighter than I like, next got a Portal Panche which is a great amp - warmer, very good detail, moved that to a second system as I wanted to try an amp with more than 100wpc and got a Plinius 8200 185 wpc (lucklily new). Love this amp, sound somewhat similar to the Portal with more umph. To my ears it fits well with my Audio Analogue Paganini CD which is warm, and my Tyler Acoustic System 2s which to me if you had to pick warm or bright lean more warm but no overly so. If you wnat to stick with 100 wpc I don't think you'd go wrong with a Panache and if you don't like it they sell very quickly on the gon when they are up for sale - check out Portal Audio web if you are inlcined - Joe is a great guy and sells new as well as units that he has loaned out, latter at a discount with full warranty and trial. Otherwise I wouldn't shrug off the Plinius off the bat.
Thanks for all the input. The only other thing I'm trying to consider is if I need balanced inputs or not. mY new CD player has XLR outputs. SHould I try to get an integrated with balanced inputs?
Watt quality makes a huge difference!!! Your speakers are 85db efficient, so you need some decent power to get them moving. Low power tube integrated won't do the trick. No mattter the power, however, you won't get the spl you have in your car with such small speakers in a larger room. You are almost in near field listening territory with your set-up. Quality of soundstage and intamacy at low volumes is what you are shooting for? Tube, hybrid or solid state? Are you looking to replace with another integrated? Your source could be part of the problem too. What are you using?
My source is the brand new Cambridge Audio Azur 840C. It is an upsampling 24but, 384khz player.
