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?

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?
My source is the brand new Cambridge Audio Azur 840C. It is an upsampling 24but, 384khz player.
I was just listening, and I know I need to do something. The system just doesn't sound right. CYmbals sound like a burst of static, and all the voices seem hollow. Midbass and midrange for the most part are fine, it is the upper midrange and treble that sound lifeless. I was thinking of trying new speakers too. I've read DYnaudio is good for rock. I have Dyn's in my car and love them. Or, I was going to goose the Sonus's with a powerful musical fidelity amp. Either way would cost the same.
So, the problem remains: Is it wiser to invest in a new amp or integrated? Or is my choice of speakers to blame? Also, would using the NAD as a linestage be effective to drive a new power amp?
Thanks for all the info. Better integrated, here I come. Any suggestions other than the Krell?
