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.

I play guitar. I have two amps I use - both are tube. I would never consider using SS. Sound is night and day to me so go figure that I seem to lean towards SS in home audio. One amp is 40W and the other is 50W. Both are very LOUD. Is there any general correlation I can make between these and the wattage I need for home audio or is it apples and oranges?
I haven't purchased speakers yet, though I've listened to quite a few. The more I audition, the more difficult the decision becomes. Since the audio dealers in my area don't seem to seel the same brand amps, I can't tell if the speaker sound I like or dislike is more the speaker or amp.
Generally speaking, what sounds better a low watt amp turned up a bit or a high watt amp played low?
I would like to thank everyone for taking the time to provide me direction and advice. Every comment has been more valuable than you know. I listened to three speakers yesterday that I really enjoyed – Dali Mentor 5 (88db), Totem Forrest (87db), and Magnepan 3.6 (85db). The dealers did not have any other Dali or Totem models and I would have liked to give them a listen. These two sounded “similar” to me. When I first listened to the Magnepans, I was “wowed”. The music separation was incredible. But, poor recordings sounded poor and they seemed to prefer certain music genres over others. They were played through an AR SD135 amp and AR SP17 preamp. But, they sounded much better with the AR HD220 amp, but that is really pushing my budget… Anyway, back to the wattage theme of my thread…. It seemed as though I needed to increase the volume on the Magnepans to get the best out of them. I’m a quick learner, and what I’ve learned here is that these speakers are not very efficient and more wattage is needed to drive them. However, does that also mean that I need to listen at louder volumes?
Dave - I live in NJ (Essex County). I visited three dealers thus far. Two were outstanding - Audio Connection and CSA. Both were very knowledagble and helpful. The first is where I listened to the Maggies and AR. CSA had the Dali's and Totem (I listened through these with Simaudio I3 integrated and Simaudio cd player - don't know the model). I really liked the Dali's but wished they had other models, such as the Helicons, to listen to. Yes, the bass seemed wooly as you say (not tight). Thanks for the damping factor. I'll try and educate myself on what this means and what to look for.
