Rockport Technologies Series 7000 Linear Tracking Tonearm

The 6000 was offered as a separate arm, the 7000 was sold with the Sirius 'table and I believe was never sold separately. I sold a 6000 a few months ago here the 'Gon. the Rockport and Versa Dyanmics air bearing linear trackers are in another performance realm compared to designs based on porous bearings like the Kuzma, Airtangent, Forsell, etc. Mikey covered this well in the Rockpoort 6000 and Kuzma Airline reviews for Stereophile.  Good luck finding any of these arms, very few are out in the wild and their owners tend to hang on to them for a very long time.

greetings,

I’m convinced Rockport Technologies’ founder and chief designer Andy Payor is a genius. The engineering and quality of his products are legendary and impeccable.

I don’t have access to the Stereophile review on the Series 6000 tonearm,
but I did read Mike’s review on the System III Sirius turntable.

I got the impression that the Series 6000 tonearm being used with the Simon Yorke Series 7 turntable was problematic in the bass frequency range .

Mike states: "I had owned the Rockport Series 6000 arm, and while it was the best arm I’d ever heard above 100Hz, its less than stellar bass performance (once I’d heard the Immedia RPM2 and the Graham 2.0) forced me to switch to the unipivot designs, despite their shortcomings in other areas compared to the Rockport."

It sounds like this area was addressed with the updated Series 7000 tonearm.

If anyone owns either of these exquisite tonearms, I would be greatly appreciative if you would share your experiences.

thanks saburo for responding to my post.

kind regards,
