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?

Phoenix469,

I definatly disagree with Mr.Reynolds. Having owned NAD from 1986 to 1990. And recently auditioning a NAD 325BEE for use at work. In my recent audition I was disapointed in the system as a whole. I attribute this mostly to the NAD, although a good piece for its price I have become spoiled. Qulity is definatly more important than quantity. Your speakers deserve the best integrated or pre/amp you can easily afford. Musical Fidelity and Sonus Faber as a combination come to mind. I have had a chance to listen to various combinations of the two numerous times in the show room and at RMAF, IMHO they make a good combination.

I agree with Dwhitt in that there are many things that make up a system and one of the most important is the room. I feel you have made a good choice with corner placement of your system. You room is by no means large. I would call it medium and square is other than ideal. Ok that said try different speaker placements with the sub off and just see what happens. You might be suprised.

If you are going to step up from the NAD do your homework even if you have to take your speakers, CDP and cables with you. It will be time well spent.

Good Luck.
Bob,

I would define a quality watt as follows. An amps ability to reproduce music accuratly without clipping or distorting. This may seem easy but without a quality power supply and a good supply of reserve power it is virtuatly impossible. Lets take a guitar if you are listening to music at say 5 watts the initial pluck of the guitar string may require 50 watts peak to peak to be acuratly reproduced. As the note decays of course the signal or power required reduces. It is the initial pluck that draws on the current reserves of the power supply.

Again a transistor or valve must not reach saturation during this initial pluck. There by clipping or distorting the signal. A transistor by its very nature will clip the signal. A valve will distort the signal. It is my understanding that some manufactures have what is called soft clipping circuits for their SS amps, so they act more like a valve amp at higher volumes. Valves and transistors have a maximum voltage rating at which point they will clip or distort. It is up to the designer to decide on what those ratings need to be to acuratly reproduce peaks in the music not just the max power of the amp.

A quality watt has nothing to do with the ability of the amp to play at ear splitting volumes. But as I said previously the ability to accuratly reproduce the music being fed to it at reasonable volumes. If you listen at ear splitting levels the only way to reproduce the music accuratly is with massive amounts of powerr and current reserves.

Hope I was clearer than mud.

P.S. My normal listening level is between 9 and 10 o'clock.
Musical Fidelity A308 Integrated or the new A5 Integrated. Looked in the classifieds no A308's listed.
