Wopl 700 series 2 with a slight buzz at midrange speakers

[Rickyboy]

I have a pair of speakers I used to use for testing, damn thing buzzed on 2 WOPL's I finished, I pulled my hair out trying to finger it out. Changed out to another set and never got any more noise. They are relegated to the "just in case pile". Damn Infinity speakers.....

how can a speaker makes an amp to buzz ?? weird , isn`t it ? in my case , the AR9`s are my flagships , so i will not change them !, Lol !!

Post several good pictures of the internal wiring dress within your amp. It matters...
Have you snubbed the bridge rectifier with caps to kill the snap off?

It's buzzing with excitement as it's so happy!

Looks like my brother's writing. He's an architect.

As for the noise, the input jacks "float" from the chassis. Float means they are not directly connected to the chassis. The jacks should have a fiber washer on both sides of the chassis. Sometimes people eliminate the washers thinking it will improve noise. I think not.
