When I have the mani phono preamp? It does exactly what you describe, that time it’s connected to my integrated viva amp.On my third system connected to Art audio preamp, it so quiet. I can’t explain why?.
POP sound when turning off TT
Equip:
TT: Rega Planar 6
Phono Preamp: Lehmann Audio Black Box SE
Integrated Amp: Cambridge Audio CAX81
Speakers: Monitor Audio Silver 300
I just swapped out the phono preamp with the Schitt Mani that I had. I immediately noticed the humming/buzzing sound was gone when absent any source. Probably a grounding issue.
However, now when I go to power off the Rega (it comes with a separate PSU), I get a loud POP out of the speakers. Keep in mind the phono preamp is still on.
When I had the Schiit, albeit a much less quality preamp, I never got the pop.
What can/should I do? Ground the phono preamp to the CAX81?
