Legacy Whisper owners - Steridian problem

Whisper owners - Has anyone come up with a Steridian Replacement??

I'm having several problems using balanced mode of Steridian. Single ended is OK, but balanced yields a hum and also a slight veil on the sound, plus a loss of immediacy. Talking to Legacy hasn't solved the problem. Debugged the system and it is absolutely the box. Tried putting Cardas converters (to single-ended) on the pre-amp end of my balanced cables and plugging into the single-ended output of the pre, into the balanced inputs and out of the balanced outputs of the Steridian, into the balanced inputs of my amp. This works, as the Cardas plugs tie together pins 1 and 3. Its obviously not true balanced, and I hate to think this is my ultimate solution.

Has anyone come up with a workaround for the Steridian? The WHispers really sound better with the equalization in my system, especially on the bass end, and I really don't want to do without it. In particular, I thought I remembered reading somewhere on this forum a while back where someone had come up with a workaround that provided both better equalization and less distortion, adapting a different equalizer and/or algorithm, etc.

Please note - NOT trying to "solve" a ground loop system problem here - looking for a Whisper Steridian replacement/modification. I also have a Legacy Focus equalizer which is not bad, but still emits some ground noise and isn't as good as the Steridian for the Whispers. Thanks for your time -
