I need a tad more weight on my cartridges to balance out nicely with the counterweight close to the pivot point.
I have seen Mpingo and graphite spacers on ebay.
The graphite one is from AudioSilente in Italy - http://www.audiosilente.com/spessori_testina.html who are currently at Munich, have all sorts of interesting looking graphite products.
The Mpingo spacer is from the seller "Asantewood".
Does anybody have any experience of these products that they could kindly share?
