A new approach. One measurement, all preamps.

THD v. Frequency for all four preamps w/ MC selected (input: .5 mVrms)... (in dB). This is somewhat arbitrary, as the Bryston doesn't have a fixed output voltage. For an appropriate level of comparison, I adjusted the volume knob to reach ~ .5 V output (the approximate mean of the others).

  • Blue = Pass Labs XONO
  • Red = Manley Steelhead
  • Yellow = Bryston BP26
  • Green = GSP Audio Jazz Club w/ Elevator
