Actually not so fine.  The Carver amp may do wonderous things, but if it
dumps trash into the AC line, it is DEFECTIVE.  Unfortunately, I don't
know of anyone who tests for this.  UL is only concerned about safety,
and the FCC presumably only cares about *radiated* noise, not
conducted. (anyone know for sure?)  The days of not having to worry
about the garbage you dump into the AC line are long gone.  Carver
should put a filter (or whatever) in his amps to prevent this.

Of course if the BSR X-10 is one of those units that puts control
signals on the AC line, and expects it to be reliable, it's even
more bogus...

prevent a reoccurance.  -sigh-
