From the manufacturer:

PU7 TONE ARM
Hi-Fi World
1ST PLACE WINNER IN THE HI-FI WORLD 2007 AWARDS!!

These arms are hand made exactly to your spec!!

The pu7 arm is available in any color or length and it has a Linn or Rega base fitting.

The arm tube is foam damped.

Adjustable height and azimuth.

The effective mass can be tuned to your selection of cartridges approx. 11 – 20 grams.

The arm lengths can be 9 or 12inch depending on what you want.

The 4 ball races are extremely high quality units.

There are 2 types of bell housing and arm tubes available, brass or alloy.

It takes me about 1 month to make 1 arm from scratch.

I’m sure my old friends at Syrinx would be proud!
