Have you tried SILCLEAR from Mapleshade?

Mrtennis,

It takes about a hundred hours of playing music or playing a break in track before the Quicksilver or Quicksilver Gold loses any tendency toward brightness or stridency. Your friend should have waited. I use Quicksilver Gold on all tube pins, including those both NOS Sylvania 6SN7GT Bad Boys. They are not bright or thin.

i cannot confirm the "break-in" period for the silclear in my friend's system.

however, as a risk taker, i would propose a wager. conduct a blind test using two identical pairs of interconnects, and i would bet that i would discern a brightness, after 100 hours of break-in when auditioning the treated pair.

Mrtennis, giddy-up! You're on.

hi geoffkait:

unless the "treated" pair creates a roundness in the treble frequencies, you will lose the bet.

of course, there is a problem of distance. you are, i believe, located on the west coast, while i live in ny.

I can't speak of the silclear but if it is anything similar to the Walker SST silver product which I tried and still have on hand I would take you up on the bet Geoff. It works in brightening things up alright but in my particular case it wasn't a good thing and was ALL too apparent immediately. I'm glad I only tried it at the RCAs into the amp, that was enough!
