Yours is different. Yours is the original version of the SA 200.2, mine is the newer current SA 200.2 ES model. I sent it back to Cary and it’s quiet there when they put the amp in their listening room, so they couldn’t figure out what went wrong and so there’s nothing to be fixed and repaired. So they sent me a brand new SA 200.2 ES and they took my other amp in on a trade and they made me pay $1500 plus shipping towards a brand new amp.
I have received the brand new amp 3 weeks ago and so far it’s been working flawlessly, no loud buzzing. It’s quiet. Wierd huh?
