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

by warmer i guess i mean, just less mechanical sounding. DC is not DC; any amplifier designer will tell you that the design of the power supply has a big effect on the sound of the preamp.
a designer chooses to use a tube rectification because they are in a sense more linear as voltage regulation devices; they do not 'switch on and off' in the same way as transistors do, leading to a potentially smoother sound.
i know my clarification is rough. if you want more detail do a search on tech square or something.
