Binding post question
 

Installed my new speaker cables today. Audioquest Oaks with spades. Because of the thickness and stiffness of the cables it was extremely difficult to get tight and now it appears the entire post assembly is semi-loose and able to spin. I opened the amp and the connection is sandwiched between two nuts that appears to be tight. The entire assembly is spinning. Should I leave it be or investigate a possible fix, not counting out replacing the posts with something a little more capable of handling cables this heavy. The thought of possible loose connections irritates me. They do sound incredible but you know how it goes....

Without a tight physical connection, I would be concerned about a good electrical connection; but that's just me.

It sounds like you DO have a good electrical connection as you describe the spade to be tight between two nuts.

To me, it sounds like the BINDING POST itself is loose--not tightly attached to the chassis.

I'd still get that tightened.

I agree with both of you, The problem is I don't feel like sending the Amp back and not having an amp just to get the same original binding post that I don't feel adequately are able to support torque and weight of cables this heavy. When I say loose I mean a couple of them can be slowly rotated. I believe the entire shaft is rotating with the spade part sandwiched and tight and the ring part inside the amp also sandwiched and tight on that same shaft. Should have taken a picture. One thing to note they do sound better than the cables they replaced , and they only loosened up during the new install. So this is more concern with a potential problem maybe down the road. Also wasn't crazy about seeing 14 AWG wire going from output stage to posts.
