Albert Porters after market panzerholz plinths

Raul,

The DP100 was very specifically designed for audiophiles. Denon sold their DN-307s and 308s for radio station and other pro use. The people at Denon's affiliated repair place are adamant about that. The Denon DN-308F is also a high-torque beast.

From everything I have been able to find out the SP-10MkII and Mk3 as are seen and used by audiophiles were specifically designed for audiophiles. The broadcast-use tables had different features.

I can't speak for the EMTs. The EMT lookalike Sony PS-X9 was sold to radio stations and audiophiles alike burI can't find any evidence they were ever used in Japan in radio stations though I have seen a couple of absolute 'beaters' in my time, which indicates to me it is possible. I know of two people, one in Germany and one in the UK who have ex-radio station PS-X9s. Most of them in Japan were audiophile-bought/owned.

The Exclusive P3 and P3a, the Onkyo PX-100M and the Lo-D TU-1000 were also very expensive audiophile-oriented high-torque tables without a broadcast market.

Lew,
The SH-10B3 (12kg) was the obsidian with rosewood base. The SH-10B5 was the obsidian-only base specifically meant for the SP-10Mk3 (round cut-out, 19kg). The SH-10B7 was the late 80s heavy (17kg) version which was meant for either the SP-10Mk3 or the SP-10Mk2A - quite like the SH-10B5, and almost as heavy (probably would have been if the cutout had been round instead of square). I do not know if there was something which made the SP-10Mk2A fit while the earlier SP-10Mk2 model did not.
