Just received my new( previously owned) Modwright Swl 9.0 Signature today. Hooked it into my system: using it with a Krell KSA 150 (ss) amp...replacing a ss audio research. Loud hum through both channels...certainly sounded like a ground hum. Spoke to Krell to ascertain that there was no compatibility issues; they assured me that there shouldn't be- which confirms what my research in various forums indicated. They suggested floating a ground using a cheater plug. Didn't help.
Next, spoke to Dan at Modwright, we ran through some troubleshooting, again to no avail. Tried disconnecting the source components, no good. Tightened the ground screws on the iec plug inlet as per Dan's advice, no good either.
Any ideas???
Thanks,
Paul
