Hi Dave,
Good question! Obtaining real 'proof' of certain audio effects, as you know, is often easier said than done, so as usual I'll go with what my ears and experience tells me.A serious question, how do you know that there are eddy currents in the supplied techie platter and, if they are, do they really affect the performance of the cartridge used? Have you been given proof of this, or is it just hearsay by others?
I've analysed in isolation the (very positive) sonic effect of removing the stock PSU from underneath the Techie platter, which for me was easily discernable. I'm expecting the reduction in eddy currents transferred from the motor unit, as a result of the effect of the bonded copper mat on the platter (and the subsequent sonic benefits), to be equally as discernable.
The sonic effect of eddy currents on the cartridge usually translates as a 'thickening' of the sound with subdued dynamics (and high frequency information), so it's fairly easy to spot in a genuinely 'wide open' and revealing system.
I'll let you know what happens, because when Guy sends me a copper mat to try, I'll be able to compare the difference both with and without with the stock platter
Marco.

Hi Mike... I'm sorry you have been slated by one of my fellow countrymen. I know of DC's reputation from my time on VE. I'm going to say no more about it other than his reputation precedes him and I have a policy of not doing business with dishonest types.
As for your ban from VE? It seems to be a favourite pastime of the owner to kick people with no explanation. I am a fellow victim, but in my case it led me to discover AoS, which is a far friendlier place to be...![]()
Thank you synsei,
No worries mate...![]()

It is the way DC operates.
A very greedy individual who has no lower limits when it comes to lining his own purse. Ethics have no place in his business accumen.
I say this from experience with reference to an offer outside of hiFi. Put simply his commission offer was some 30% above normal practice. It didn't take long to find out someone was all for lining their own pocket.
Suffers from dilusional granduer and over familiarity.
Nuff said
Hi SF
