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?

My source is the brand new Cambridge Audio Azur 840C. It is an upsampling 24but, 384khz player.
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?
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?
