Great OSD Audio ATM-7 Speaker Selector Switch - Carver M-400 killed

This is a great Speaker Selector Switch. I love it except for this one design choice.
Common Grounds for Left then Right
This should only affect certain amplifiers like the carver magnetic field amps.
Anything with a hot that goes to chassis ground, will be shorted by the common. An amp that is hooked up with the Carver amp will backfeed even if it's on a different zone.
I had a standard amp fed on zone B Then the Carver on zone A, and the zome B app fried the Carver.
Please make a ATM-7 Pro with every terminal independent from source to output. This way it would be faultless! It would only pass whatever the amp or speakers are doing.
This can be especially important with these amps as well as the Polk SDA SRS speakers. In addition to possibly maintaining whatever channel separation the system would normally have.
