 I have been using Jelco SA-750E 10" tonearm for the past five years or so. After recently upgrading my front end to Dr. Feickert Analogue Woodpecker turntable and Kiseki Blue NS cartridge, I've realized that Jelco may not be the best fit for that combination.

What would the learned peers on this forum recommend as a good upgrade path from Jelco?

 Looks only a mother could love.

Quite the reviews (lots of "astonishment"!) and the price is right.

 I'm not in the market for a tonearm but if I was ready to spend that kind of money again I'd have the Supatrac 9" arm on my list of 'arms to check out. It might work well on a Gyro SE.

The design logic and materials selection seems reasonable.

Moerch DP8, maybe the black version to match your table.
I put one on my Orbe TT and love it. On the fly adjustable VTA, easy azimuth adjustment, and can be used with various available arm wands to alter the tone arm mass (including 12 inch wands) to accommodate different cartridges.
About $5K depending on the version. Sorasound is the dealer/distributor in the US. Mehran is great to deal with.

 I bought a Jelco and took one look at it and sold it immediately. This thing looks like somebody worked in an extrusions shop and owned a hacksaw and some black paint.

 Keep your eye out on The Tracking Angle for a possible Fremer review. Richard was at the Munich show and Fremer was very interested in getting hold of one for review.

It's an elegantly simple design and a clever reinterpretation of a unipivot and solves at least 2 of the main problems with a conventional unipivot - which is lateral roll and azimuth consistency.

I've discussed the design with Richard and there are still some flaws IMO - the bearing is not offset so the azimuth is going to shift as the arm rises and falls on a warp or you use a different record thickness. The second is around the antiskate solution - it relies on the arm suspension providing the necessary torque. Although Richard is working on an antiskate solution, the suspension adds to the torque over at least part of the travel.
As to whether these are issues to anyone else will depend on the individual, but to me there is still room for improvement.

 I'll keep my eyes open for that review.

As for the inherent problems you mention, such as "...the bearing is not offset so the azimuth is going to shift as the arm rises and falls on a warp or you use a different record thickness", I use a VinylFlat for warped records and I use platter mats to maintain a fairly consistent record surface height.

But the other problem, that the anti-skate tension "...relies on the arm suspension providing the necessary torque" would dissuade me from buying that 'arm. At least until an anti-skate mechanism is incorporated.

But I'm not really wanting to replace the SME 309 so it's more out of curiosity than need. :-)
