Mine is an integrated AB push/pull pentode, but I'm sure the above applies. It runs warm even at 10% volume.

My impression from this thread was to set volume on the SB3 to 40 to disable all volume control algorithms. I would much rather use the SB digital volume control if there is no manipulation of the signal, but i assume the added bits for the volume algorithm are considered 'bad'. Sorry for being dense, but was the verdict that for FLAC, LESS than 100% volume(40) is better or worse? Would you always want 'more bits', or would it depend on your DAC? Again, apologies. This is probably covered elsewhere. DitherMan Wrote: > Tube amplifiers normally have higher input impedances so that the > loading effects on a passive volume control are less important. I'm not sure if this means the digital volume is better than the analog. Does the SB volume go from being active to passive when less than 40? I understood your point that an A/B amp is in class A at 100% volume with low signal input. However, I also don't want to crank the Alps Blue pot to 100% (if that is the same as "connecting directly to a power amp") because of potential speaker damage.
