does more power=better quality ?


in term of sound quality in amp? does more power give you better quality.I understand it give you better control of the bass. how about mid and high?
is a 300watts ( krel, levinson,rowland, audio reserach ..etc ) better than a 200 or 100 watts model within the same company and product line? what if you have a relatively efficient speaker?

"there are fewer output devices to muck up the signal" is it kind of like thecar analogy.for the uninitiated ,non engineer . can you use the analogy of a car.just because you put V8 engine, the car may accelerate better but it doesn't always handle better. some peoplle may preferred a mini cooper vs a corvett because they feel the mini handle's better.
Hey Raquel, I am shaking my head now too after selling my Krell 750 monos, KCT and Wilson MAXX for the VAC PHI Preamp, VAC PHI 220 Mono's and a little pair of Caravelle Monitors supported by a Velodyne DD-15 inch sub! I have never had a more dynamic, musically satisfying system in my life with the most unbelievable depth of soundstage I have heard in any system anywhere. More money and more power doesn't always mean more satisfaction. I learned the expensive way!
The problem with all the comparisons to 8 watt SETs...
is that "all else is not equal".

Philefread,

Your 8 watt SET amp IS "loafing".

That 300B tube is capable of more than just 8 watts.

That tube can be used in amps putting out on the order
of 40 to 50 watts. For example, Cary uses it in a
15 watt SET power amp:

Therefore, in the context of my discussion on linearity -
the tube is not being taxed at all.

Your 300B SET amp is not limited by the 300B tube - it is
limited by the power supply.

The designer / manufacturer of your amp put in a low power
power supply - so you can't push the tube to anywhere near
its capability.

The manufacturer forced the tube into "loafing" by pairing
it with a relatively "anemic" power supply.

Your speakers may be relatively flat - but they don't have
an absolutely flat 8 ohm impedance. Do your speakers have
voice coils? Voice coils are inductors - and the impedance
of an inductor is not flat - it varies with frequency.

Raquel,

The problem with your argument is that in amps in which
there are more than a single output device; the output
devices are in parallel.

No - the signal is not going through more circuitry - all
the electrons see the same amount of circuitry. It's just
that all electrons don't see the same components.

If you have a tube amp with 2 paralleled 300B tubes; all the
electrons saw a single 300B output tube - just not the
same one - 50% saw one tube, 50% saw the other.

The comparison at Singer is worthless. A VERY BIG factor
is the size of the room. One was smaller, one was larger.
The rooms therefore had different resonant frequencies -
and Lord only knows how that affected the sound.

You can't conclude anything even remotely meaningful from
two different rooms, with two different speakers, with
two different amps...
