Hi Guys
Yup, Ive used them for about 12 years or longer. I have two in use - 1 in my listening room and another in my cartridge testroom. One is fitted with a Micro carbon fibre arm and the other with a Grace Gyromaster G727. the first one has my own design acrylic plinth system and the other is 'plinthless, sitting on 4 aluminium legs with butyl rubber cone feet which is adjustable for leveling. The 'naked' 301 has its arm mounted to a 'mini' pearshaped acetyl and aluminium armboard, providing total arm isolation from the tt base and mechanicals.
Pics (jpeg) are available if I can load them to your Gallery.
Cheers
