Basically in a class a or b amp you are listening to the power supply modualited by an input signal. in other words the powersupply is the floor and its supposed to be flat and level. IMO filtering makes more differnce. RALPH.....RALPH!!!
Tube vs. Solid State Rectifier
How much does the rectifier stage effect the character of an amplifier. So far, on nearly every SS/Tube decision that's come down, I've gone with tubes. Now, I'm looking at two 300b push-pull integrated amps, the main difference between the two is that one puts out 18W/ch and uses tube rectifiers while the other puts out 25W/ch and uses SS rectification. The SS unit has a much greater bandwidth and just specs out better in general. I'm leaning toward the SS rectifier as long as the amp will still have that tube magic. Your opinions will be appreciated.
