vibration control

The self delusion is that you think there shouldn't be difference.

The wire is the same but the terminations are differnt, and how did you terminate them?

You used bananas.

Had you said you used bare wire termination and noticed a difference I might have said there would be likely to be a marginal nod to the newer less tarnished run of wire.

I suggest you take the bananas off and listen again.
You may also hear an improvement and if it lasts longer than 3 hours then you know your not delusional and that the bananas did affect the sound of identical lengths of the same wire.

I would also suggest that you try a set of bananas from WBT such as the nextgen and have a listen to their effect and compare them to the sound of the bananas that you tried, but something tells me you won't bother with that.

You missed the point of the post. I was replacing locking bananas because they were a pain to remove from the amps while in the rack. My point was to show how easy it is to imagine something that does not exist. I was not seeking or expecting a difference in sound. So to save you the trouble of sending a reply, I'll just say it for you....... 'Never Mind'!!
As far as trying the plugs from WBT, something told you correctly.

Look at the audio brick test using a genuine McIntosh brick.....http://www.roger-russell.com/truth/truth.htm

The BEST vibration control I found was inside the gear not under it. I took off the top cover and put four layers of Wal-Mart brand of teflon tape all around where the screw holes are on the top chassis for the top cover.

Next, I took off the bottom plate and put four layers of teflon tape all around where the screw holes are on the bottom chassis for the bottom plate.

You don't put any teflon tape on the top cover or bottom plate parts, you only put it on the top chassis and bottom chassis of the gear only.

I did this tweak to my Yamaha a-s2000 integrated amp it now sounds much more musical !..

This is a must try tweak for all your gear !!

Encase the entire component in cement? With openings for the cords and controls of course.
