does more power=better quality ?

correction
i mean i was NOT comparing sony to levinson amp

S7horton,

Let's take the comparison of the Classe CA301 at 300 watts
and the Classe CA201 at 200 watts.

If the design of the amps is essentially the same, and Classe
selects components with the same quality; but it just puts
more transistors in the CA301 than it does the CA201; then
yes.

For the same load, the transistors in the CA301 will each
be providing less current than their counterparts in the
CA201. Therefore, because the transistors in the CA201
are putting out more current - they are farther out on
the transistor's response curve. Depending how linear
that curve is - indicates how much less accurate the CA201
will be than the CA301.

If the curve was perfectly linear - then there would be
no difference. But real transistors never have perfectly
linear curves. The CA201's transistors are extending
farther out on the curve than the ones in the CA301,
because the CA201 has fewer transistors to carry the same
load.

The difference may be marginal, if the transistor's
characteric curves are fairly linear; but there is a
difference because the curves for real transistors are
never perfectly linear.

My 300B SET puts out a whole 8 watts. It's playing 98db speakers with a flat 8 impedance. Hm! Would you say it's loafing? It sure sounds better than any high power amp (Tube or Solid State)that I've owned or had the pleasure of listening to. I've heard some pretty good S.State high power driving stats. or other difficult speakers also. It's about having the right gear for the grade!

With apologies to Anarchy with whom I disagree on most everything, all other factors being equal: yes. The more clean power the better. If you listen to the call of the sirens you will get just the opposite view and may wind up with a two watt SET!

P.S. And insofar as the ambulance chasing bit from Anarchy, why not come up north and tell me in person.
