I was turning off my system and noticed it disappeared when I turned off the Bel Canto
If that was the last thing you turned off then its the amp. If its still there even with everything disconnected from the amp, confirmed.
Help: Unidentified high-pitch sound
Hello---I'm hoping someone can help me identify the possible source of a intermittant high-pitch sound coming from my left speaker. So first of all, here's my system:
-VPI TT
-Modwright SWL 9.0 AE preamp
-Bel Canto REF500s amp
-Marantz 8006 CDP/streamer
-Dynaudio Special 40s
-WyWires ICs
My system is only about a year old old and up until a week ago, everything has been just fine---beautiful music. I usually hear the tubes warming up for the first couple of mins with a little 'ping' sound. But then I noticed a slight but audible high-pitched sound coming from my left speaker---nothing on the right. I had been listening to the streamer when this happened. So I switched the sources on the preamp and still noticed it no matter what source I picked. But sometimes it did disappear while I was switching the source. I don't notice it when the music is playing---but when the song stops, I hear it. Then, a couple days ago, I was turning off my system and noticed it disappeared when I turned off the Bel Canto. So is the source the amp or the preamp or something else? Thanks so much for any advice.
