So yesterday I got my 2nd set of these footer beauties.

(gold colored aluminum body, 4-pack, ceramic bead type that come with free steel beads from Hi IC Store)
Having received great sound trying the first set under both my power conditioner and amp, I thought it would sound
good just like what I heard before when adding this 2nd set under the amp to compliment the other one.
WRONG! This sounded downright
spectacular, not just
good. These things are no joke, the full monty. Imaging, bass weight, high detail & focus snapped into place like I never knew they could on my meager system, and just like my subconscious seems to have been begging for. It seems multiple sets of these these things play very nicely together - not just geling well but each set expands the benefits of the other. For me it was just 'set & forget', and I didn't even bother trying the spare set of beads (yet). And these sound better to me than 2-3 other types of rubber dome shaped feet, sorbothane sheets of different types, & plastic / rubber pucks I've tried as well.
Also I've read something here about coupling & de-coupling footers. What does that mean, and which do these happen to be?
There it is folks, there are more than just cables & tubes when it comes to upgrading a system.
