Re: Counterpoint Preamps: SA-3.1 vs SA-5.1 ???

Please school me.. How on earth can a tube power supply make the
sound warmer? It's just supplying DC to the Preamp right? Tubes
in the signal path I can understand but I can't imagine how DC makes
a difference. Now if you said it was a cleaner supply of DC with
less noise I could buy that but warmer?? How??
