Switch to silver for a treble boost?

Douglas, thanks for the info.

Carl, try the Caesarstone. There are two purposes I think for the platform:

1. to increase the mass of the CDP and it's shelf in general to dampen outside vibration, and

2. to absorb high frequency vibration from the player and dissipate it in the structure of the platform.

I would predict that stone would do the first thing as well as or better than wood. I would think that wood and stone would do the second thing very differently, and you would have to try both of them to see which you like better. My prediction is that stone would have a brighter sound signature than a wood platform. Good luck with your experimenting.

Silver has absolutely nothing to do with treble sparkle. Some silver is neutral sounding..some have rolled off treble, and some...only some have a high end "sparkle"

Silver speaker cables arrived... initial feeling is that they have made little difference to the upper treble, as a couple of you predicted!
My system still seems to sound as if there's a sheet over the speakers.
However, they did alter vocals in a nicely unexpected way. To my ears, voices now seem better defined and separated from the backing music, as if the singer has taken a couple of steps towards me, and this was using a few of my favorite and familiar tracks.

I might report back again after a few more days listening.

Carl, I tried a similar test to get a little more treble "air" and went with the popular silver Signal Cable.
The results were less than stellar. I found the cables to be less transparent overall. I'm VERY skeptical of mega buck cable's and thier supposed differences, but compared to some Nordost cables which I recently borrowed from a local dealer, the Signals just sounded more laid back and slightly veiled. This may be suitable for some but when looking for a bit more top end "sparkle" the silvers failed.
Good luck in your findings

Alun, after a few weeks of the silver speaker cables (locally hand made from "German surgical grade silver" according to maker), I have to agree. The difference from my previous heavy copper was small indeed, but I accept that could also be system related.
The silver has produced a slight lift in the upper-midrange, which has helped nicely with vocal clarity, but certainly didn't produce any extra treble distinction or "sparkle" that I was hoping for.

I would add that these cables (2.5 meter pair) were only $100, but given my system I'd be reluctant to spend more than that.
