Hello @georgehifi
We've had a similar discussion about preamps:
https://forum.audiogon.com/discussions/bypassing-a-preamp-with-volume-pot-in-amp
I knew I've seen that Nelson Pass quote before.
I have had great success "bypassing" a preamp with a Khozmo stepped attenuator using Z-Foil TX2575 resistors inside an amp.
I ditched the volume attenuator completely in my current setup and only control the volume from the computer. I prefer to lose a few 1s and 0s from the computer volume than to add a preamp that brings so much favorable and unfavorable distortion/coloration from tubes, resistors, capacitors, regulators, diodes, interconnects, power cords, etc.
Who needs an preamp when you have a Pass XA25? (jk) This amp is amazing.
