If it worked well before, and you didn't do anything new.....added, removed Anything.....it needs to go back to the manufacturer for a look see.
Audire Diffet 1 hum
My Audire Diffet 1 preamp recently developed a hum audible through the speakers. Still sounds very good at volume, but probably like all of you, it bothers me. Could it be a transformer, capacitor or otherwise?
PS Audio had a nice article on isolating a hum, but didn’t mention the possibility of equipment. I guess my question is it probable that the problem is external to the preamp, like interconnects, or line voltage? (My other system doesn’t have a hum). Oh, and it produces a thump when the amp and preamp are turned off together (I don't do this anymore).
