Should cable elevators be used?

Only if the cables are unable to make the stairs....HA, sorry, I could not resist:) Some here devise their own, utilizing household discards, up to the imagination. There are ideas regarding such via forum search, here. If/when I decide to experiment, I would try a collection of old (pole) wire insulators. Very interested in your findings should you experiment.

I do the same as Elizabeth and noted a minute change but price is right!

a half roll of Charmin sounds the best. It increases the damping. Plus the highs are softer.

I just got some ceramic ones and thought they made a worthwhile improvement. I am currently recruiting a group of leprechauns to install and remove them while I am listening with my eyes shut so I can see if I can really tell the difference. That ought to make the blind test gang happy. Don't get the Mapleshade ones; three large Tinkertoy sticks with a napkin ring. Or I'll sell you mine if you want your patience exercised.
