Hi music lovers!
I´ve had the copper mat for some weeks and think I got a good idea of the sound. Immediately after putting copper mat on platter I noticed a more clearer sound over whole spektra and it still remains. Bass more distinct/firm, mids and highs clearer with more details.
Speed stability I can´t notice much difference, maybe on less advanced system there could be an improvement due to inertia of gravity (it´s more difficult to affect a heavier platter once it´s turning)
I´m satisfied and think it´s a cheap way of upgrading.
Besides, it looks more pleasant and the mat is tightly stuck on to the platter spindle with zero tolerance.
For 250 bucks it´s definitely worth a try, I got it for 139 bucks via auction on audiogon.
Many Thanks!
