I have a buzz

I am buzzing. I had high hopes for this thread. High hopes indeed. Now I am just humming.

How loud is this noise? Is the noise noticeable only when youre close to the speakers? Try unpluging ICs (turn amp off 1st). Is the amp faulty?

It's strange, Audiofeil. From my experience buzz always happens in the morning and than gone by 6...7pm

"I had a buzz last evening.”

I have to confess Bill, I had the same thought when I was browsing thread titles. It was like - "Whoa! This will be different, maybe I should go look for my lava lamp"... you know, just to get into the spirit of it.

I had a similar issue and switched IC's which solved the problem. Unfortunately alot of trial and error before that.

I had a buzz last evening.

It was gone when I woke up today.

Will try again later.

This is a cheater plug:

What is a cheater plug? And the Klispch are very efficient.

You probably have a ground loop. Assuming that is correct you need to identify the source. I suggest you not only disconnect but unplug everything connected to your amp (except the speakers of course). Turn the amp on. Any buzz? I suspect not, but if you do its likely something is wrong internally.

Assuming there is no buzz, plug in a component (do not connect it with IC's). No buzz? If not the turn off amp and connect IC's. No buzz. Repeat process with other components until the buzz appears.

When the buzz appears attach a cheater plug to the PC on that component replug in in and see if the buzz goes away. If it does you are in hog heaven. It is not unsafe to operate your system so long as the amp is fully grounded.

If nothing eliminates the hum and the hum is really low in volume, i.e. heard only with your ear at the speaker grill, you might have just heard the amps noise threshold. This is not uncommon with very efficient speakers and its not a big deal.

Your power line may have a ground fault.
Try to block loose ground wire with cheater plug or ask electrician to take care of the problem.
