Romy,

Thanks for the advice.

Just to be clear here :

When you say

"Short the ML2’s inputs and the hiss should be gone"

I assume it is not a mistake, and that you mean short the unused input on each POWER AMP (as opposed to the PREAMP).

(I am currently using the XLR connections because I don't have RCA cables in the correct length)

Is there any advantage (or danger) in shorting the unused INPUTS on the PREAMP?

For the moment I have metal sheilding caps on all unused inputs (pre and power amps), which don't seem to make a difference.

The ground is lifted on all equipment and and attached to a water pipe. There are 5 dedicated circuits, located in a dedicated breaker box fed directly from the line that comes in from the street (that was fun!).
