RichP714 has modified the ones on the Mk.II amp. IIRC, the hole was a little too big, and he had to use a washer with one side ground down. I did my M-500 amps with the same posts and did something similar. I had a depth problem and had to saw off two of mine, but I think it's just a problem with the M-500. You only have to go through a sheet metal panel, so I don't think the short ones would be a problem. You always have problems with longer ones running into components on the inside. You probably should look before you jump.
It should sound like it isn't there!
There is a difference between hearing and listening...
