While there are probably several that would work, why not mention which ones that you have tried or are using now so that we dont mention them again ?

Seeing that you have been a member for a while now, and have plenty of feedback, participate in the forums, I am sure you have tried a few tweaks here and there.
I use stillpoints, doesn't really extend the high end but makes it more defined, improved sound stage depth and adds clarity. I have at times tried to remove the stillpoints as I struggle with $1200 worth of little black cones under my equipment but the stereo is just a little shallow without them. They seemed to make the biggest difference under the amp, then preamp and phono then CDP. But a difference under each.
Brass cones:Audio Points,Mapleshade or the Bear Claws.All available used and the BCs are available thru AudioGon.
