Whats with the Watts ??


Hi everyone. I'm starting an audio system for the first time and I've been doing my homework -- reading and listening as much as I can. Sorry if I ask some dumb questions along the way...

One aspect I'm very confused over is how much power I need in an amp. So many highly rated amps seem to be in the 50 watt range, yet there are also those in the 100's of watts. My room is about 25 x 15 with a ceiling that slopes from 8 feet at one end to about 18 feet at the other end. The room has 3 walls but opens up into a foyer on one side. I listen to all types of music, but mostly blues, jazz, and some rock. I like to listen at low to medium volumes. Its rare that I would play very loud. If it's important to my question, I seem to prefer the sound of solid state amps.

Being uneducated on the subject, my initial thought is, get more watts. Better to have too much than too little. So my questions are; how many watts should I be looking for and is there something to be gained or lost with too much or too few watts? Thanks.

Most SS amps have negligable output impedances, thus relatively high damping factors(Use the shortest cables possible and/or true bi-wire cables). Few will have the midrange liquidity or sound staging of tubes though. I'm using a Hafler TransNova 9505 for my woofers, and could live with it full range(if I had to: MOS-FET output). Bryston makes good stuff. Balanced Audio Technologies, Plinius, and Edge(excellent SS) are all available used on this website at reasonable prices(pay attention to feedback of seller). Moscode has a tube driver stage/MOS-FET outputs and they offer a risk free, in home audition: (http://www.moscode.com/) You can roll the tubes for even better midrange and sound stage with that option, and still have excellent bottom/high output(read the reviews). Here's another source for used/demo/new sealed stuff, either tube or SS: (http://www.upscaleaudio.com/view_category.asp?cat=31) Kevin is reliable/knowledgable.
More info on the Moscode:(http://www.stereophile.com/tubepoweramps/606moscode/index2.html) (http://www.avguide.com/products/product-3459/) Download the review on TAS page. If I were to go with a single amp system, I would probably audition this first(can't lose).
What are you thinking about with regard to a preamp? An integrated would simplify the system/eliminate an interconnect. Musical Fidelity and Chord build some excellent units.
Silver911, a system must be synergistic otherwise it will disssapoint! Many people will offer suggestions. I offer a suggestion that will put you in the BIG LEAGUES for a minimal outlay of cash...Totem Forests, Krell400xi, MIT cables and a decent front end of your choice ala NAD M series, Rega etc... A great power cord will also do as much for your system as anything else will!
