Hi,
Just to clear out some points, so we can have a base line of understanding:
1. the MF amp does the the 6 second mute and the come up. when it comes up the speakers pop.
2. the "shhh" sound comes from any source I select and even with out any source connected to it
3. All my devices are currently connected to a Power conditioner (Keces BP-2600) that does check the ground connection.
4. Disconnecting the Marantz I also have the same "shhhh" sound
5. I have a Moon 280D connected to the CD in of the MF M3i, and on quite music passages i can hear the "shhh" up to some level.
@noiseboy72 when you say:
"I assume you are running out of the Marantz into the MF and then to the speakers using the HT / Aux1 input set to HT? In this scenario, you are bypassing the pre-amp stage and volume control, which contributes most to the hiss, as this is where the voltage rather than current amplification will happen."
I have not tested the amp with the "HT/AUX1" set to "AUX1", but would assume this issue would be unrelated with it. Do you know if just by setting the "HT/AUX1" to "HT" is a condition that in general introduces noise in to Amp?
Many thanks for your help
