Pass Labs and Steel cones ?
 

Hi, i have saw many amps pass above the cones.
What is the improvement ?
I'd like turning steel cones to try :scratch2:

You should try Ultra 5 Stillpoints.

try with nordost sort kone BC or TC

Seriously? At $2800 for a set of four, that's a good chunk of change.

i have saw "cold ray ceramic"

what's even stranger are the folks who will spend that before addressing room acoustics .........totally absurd !

In my case i use for my X600 monoblocks 3 units of Nordost Sort Kone (1 TC under the toroidal transformer in the front and 2 BC in the back).This mix of different Sort Kones was recommended by the distributor of Nordost in France.I have the luck of meet in person this gentleman in my last vacations in Paris this year in AudioSynthese high end store and he tell me that this combination of different Kones is, in your opinion, the best way to use this incredible tweak.The same mix for CD players/transports with the TC Kone under the disc tray.
Hope this helps
