Just saw an ad in a Hong Kong audio mag, Audiotechnique, that there is a distributor in Hong Kong for Shun Mook products - www.wiwitubes.com. I know that Shun Mook was operated by a few guys from Hong Kong here in the SF Bay Area. But I also recall some report many years ago that this place had sold some fake tubes.
I had tried several record weights and found the results to be surprising. It affects the sound more than the outer ring. I had purchased a DIY weight made out of some African Ebony and it sucked out all the bass. HRS is the most benign one. It sounded good on almost any type of music, and on any table. I had recently purchased a Malaysian Ebony weight from eBay. It sounded very nice. It added some air to the sound, and the texture of wood body on instruments like guitars, violins, and cello. A friend of mine, after hearing it, bought the heavier one, and he preferred it over the Kuzma ebony weight.
