Tri-Planar Vll "SE Upgrade"

Geoffrey Owen uses rubies as the bearings in his fabulous Helius Silver-Ruby Omega arm (the arm Tim de Paravicini recommends for use with his EAR Disc Master turntable), and silica nitride as a more shatter-resistant alternative. Extremely hard and smooth, sn is perfect for use in tonearms. Hard and smooth equals quiet.

Dear @bdp24 : EPA 100 models by Technics uses 20 of those rubies in its bearing. Terrific tonearms, very high quality performance levels.

SME uses ABEC 9 bearings. Brickman are very good too. I think that today there are no true bad tonearm designs.

As the GST 801 the EPA ones are four point bearing. There is lmost nothing new with pivot tonerms designs but the Thales Statement design that is  true evolution in pivot tonearm designs.

Dear friends: Not only here but through other threads ( different or similar subjects. ) were  exposed/spreaded/posted  several lies that per sé is totally dishonest. Lies in favor of what? because here are facts that proved those lies and inexperiences  as in other threads too.

@tri-planar is not the guilty about but only a " victim ". In the site there is no spec for bering tonearm horizontal/vertical friction and its measurements about.

Btw, the AT tonearms came from the 70's and HP started in the early 80's. Whom copy whom on that: " same plane " bearing/Lp surface ".?

In reality that copy word exist only on those tonearms I mentioned were a true copies.
