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.

Sonus Fabers lower models need an upfront and dynamic amp or else it would sound as what you've described. Also, since you listen to mostly rock, you would certainly need to look at the amp. Primare and Plinius are not good choices are they are on the lush and warmer side of things. I would suggest a Krell integrated. If possible, try to borrow a KAV-300i and see what it will do in your system. It brought back life and dynamics to my Grand Pianos which sounded like dead speakers with my Plinius amp prior to auditioning the Krell.

I have owned Sonus Fabers before and share your same thoughts. Although I still can make them work, I chose to get rid of the speakers and find some new speakers that are more neautral. It's your call on whether to work on the amp, or the speakers.
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.
