Hum coming from Left and Right channel - RCA to XLR Adapter


I have a Classe SSP-800 processor which runs through a Gryphon Diablo 300 Integrated amp for the left and right channels. The other channels run through a 5 channel Krell TAS.

Historically I would run my Home Theater through a Ayre PreAmp which had XLR Inputs for L/R Home Theater Bypass. The Gryphon only has unbalanced RCAs for its Home Theater Bypass.
For some reason I get a humm out of both the left and right channels when watching a movie--Its not loud, but still annoying. I upgraded my cables, but still have the humm.

Since I never had this with the XLRs I was thinking of trying some XLR to RCA adapters out of the processor so I didn’t have to use the unbalanced connectors on the processor. Thoughts? Do these work that well.

There is not a humm on any of the other inputs on the Diably 300 so I suspect it is the outputs out of the SSP800.
Thanks!

Al,  Thanks for the very thorough response.    Sounds like i was definitely headed down the wrong path.   I'll give the Jensen transformers a try.
