Same issue, some pre-amp. Same time. Just want to insure I'm not duplicating my replies to the same person. I've already replied on the subject, at great length and significant personal time, to the other thread started by @emergingsoul.

When HT bypass is engaged, the pre-amps volume control has no effect on the signal that is being passed-through. A passive output is basically a volume attenuator. At full volume, it will pass-through exactly what is received at the input. However, the volume control will affect the signal, so anything less than full volume, the output will be attenuated (less than the input). A passive output is not unity gain, except at full volume. At anything other than full volume it has negative gain (volume attenuation).
