Vibrating speaker cables

If your system or your ears are not up to the task, just move on. OR come over here and hear the difference. But sheesh,, whats with denying others experiences?? You tin-ears would freak when I tell you moving aftermarket footers to different configuration underneath a component also changes presentation a bit. These changes are not always positive or negative, sometimes just different and sometimes only where things reside in the soundstage... but you last two posters can’t hear good enough or don’t have good enough systems anyway, so what’s the point. 

If you deny realities that yourself or your system can not render out, then read no further.

 This thread intrigued me enough to look and try something with whatever I had around... I use Triode Wire Labs SCs (so nothing to fancy) on Harbeth 40.2 Anniversaries. Like most SCs, the TWL’s have 6 or 7 inches of separated pos/neg leads at the ends. I have some Herbie's Audio Labs Tenderfoot footers sitting around unused, so at the speaker end, I gently pushed one of these between the two leads as far ‘down’ as I could tightly get it to where the two leads converge into the sheathing; the tapered shape of the rubber footer was good for this fit... It worked! I hear more clearly, quite a bit less bass distortion and better speed/timing. 
 There are two specific/different placement approaches with the 40’s and I’m in the middle of trying to hone in on the other positioning I haven’t been using, and this just helped quite a bit, showing me I am not as far off as I thought I was. Hearing less bass distortion, which is allowing every bass note to be presented evenly and with much better clarity and decay is very nice. 

I could probably uses something better than the temporary footer but I don’t what that would be yet.

I have the same cable lifters as you, @millercarbon, and am definitely going to hunt down the right size rubber bands. Do you have any idea what size around your yellow bands are??

Id also like to maybe find or make some heavy beanbags (lead shot or sand or what??) to rest on top of  the speaker cables at the lifters to see if that does anything further...but so far, ‘stiffening’ them near the binding posts is indeed working.

@facten Oh I gotcha!

@facten i wondered if the pipe insulation would be dense or tight enough on the binding posts to do any dampening. Maybe tightly wrapped in electrical tape or something? Still might need something more dense. 
This is clearly dependent on speaker design/construction. My harbeths are made to resonate; its part of the design and worked into the frequency response. And turns out, with the Herbie’s footers snugged tightly between the two speaker cable leads was to much and after posting I noticed a new hardness to the sound, so I back them off a bit (a less pressure)... Definitely a weird and sensitive thing with these speakers.
