Low level buzzing coming from tweeters.

Got balanced cables as i now have a balanced preamp Purist made my single ended cables balanced buzzing is now gone.I will now used balanced always and use Purist always.Thanks!!!!

Nice to know you solved it, ebm.

Mine is a different problem, probably my amps. Even disconnected interconnects, unplugged everything except amps, turned off all circuit breakers, except those dedicated to amps . . . still buzzing.

@ncarv  Short the inputs to the amps- if not shorted and no input, a buzz might be normal.

Read the thread buzz is gone using balanced Purist cables!!

atmosphere - I appreciate the suggestion. My tech guy, extremely knowledgeable and competent, but who no longer lives nearby, suggested the "no input" test. He knows the amps, having extensively worked on them, suggested trying without inputs. He said there should not be any buzz with the inputs removed. The amps are old VTL Deluxe 500's and, though the caps were replaced, there is some transformer hum. I'm wondering if it has just gotten worse over time and is transmitting to the speakers.

ebm - The amps do not have balanced inputs, only single ended. In any case, I'm using all Transparent Reference cables, so I don't think that should be an issue.

I'm going to hook up one of my Anthem solid state amps and see if that makes a difference.

Thanks to both.
