Great bass from a linear tracking arm?

Rual, I take note of the fact that you say you want to build a (the best in your words) tone arm.

I was wondering what your opinion is on the bearing design. If you do go ahead with a pivoted tone arm design, which type of bearing are you would be considering? Also, would your design be influenced by any existing design?

I am asking because you have a good mix of designs in your collection and are very familiar with the differences in design.

Thanks
Paul

Dear Paul: That will be gimball or similar not unipivot. The design/build of a tonearm is far from be an easy task " there are a lot of black magic " there.

We are on the research on bearings, materials, geometry, resonance, vibration, balanced system, etc, etc. . In the next 2-3 months we will have our 2-3 first different prototypes that we have to test against other tonearms and with any cartridge we have at hand. These kind of work will be a very long time consuming before we will really sure where to go.

+++++ " (the best in your words) " +++++, like our Essential 3150 Phonolinepreamp design our target is that. We don't attemp to design/build something " only a little better ", our approach is the best one and the best one for all audio people. We don't know if we can achieve our very high targets about but we will try hard to meet those targets. We hope that God give us the strenght to be there to really help at the music/sound reproduction.
Like in the Essential 3150, we are designing with out any commercial or other kind of compromise, like always our compromise is the: MUSIC, nothing less.

Regards and enjoy the music.

Very good. Thanks to everyone for their responses.

After getting my ET2 arm dialed in on my VPI HW19 Mk3, with a little help from Bruce Thigpen (a benefit from living in Tallahassee),I find that the ET2 is delivering excellent bass response, and that's using a well broken-in AT-OC9, which is not at all a light cartridge at 7.8 grams. Also, I might add that the bass is much better now, as well as the overall presnetation, than with the same cartridge in my Linn Ittok arm/LP12 table.

If you have any doubts on what works and doesn't on air-bearing linear-tracking arms, send Bruce an email and I'm sure he can help you out. After all, he invented it and cousults to those who build them.

Rauliruegas,
