Best tonearm under $2k


I’m looking to upgrade the tonearm on my Acoustic Solid Bubinga wood TT. It came with a Rega Rb330 tonearm and although it does a pretty good job, id like to squeeze out a bit more. I just replaced the Denon 103r cart with a Soundsmith Zephyr MIMC Star cart and I don’t think I’m realizing it’s potential. I also upgraded my phono to an EAT E-glo S which I think would also benefit from an upgraded arm. My power amp is an Audion 300b Silver Night Special Edition driving Zu Soul Superfly’s. 
I’ve got one dealer steering me towards the Jelco 850s and another dealer suggesting the Sorane SA 1.2 tonearm. 
Does anyone have any listening recommendations on either of these?

Thanks,

Rick

Rick, there is no getting away from physics. Effective mass and compliance determine the frequency the suspension oscillates at. You can dampen the oscillation with various damping methods like a paddle in viscous oil but the frequency remains the same unless you change either compliance or effective mass. You want that frequency between 8 and 12 Hz. I like to keep it under 10. Below 8 and you start getting into record warp frequency. Which means when your cartridge hits a warp the tonearm rockets skyward comes down and bounces back up again and if you get it just right it will keep bouncing till it jumps off the side. Get it above 12 and you start getting into low bass causing feed back and softening bass transients. Origin Live might not be concerned but you certainly should.
Agrippa you and I obviously live on different planets. The Jelco is a fine arm for the money with medium to lower compliance cartridges but it is no where near as sophisticated as the SME 309 with its tapered arm tube and aerospace bearings. The SME is much lighter and therefore adaptable to far more cartridges. It is easy to add weight to an arm. Not so easy to take it off. I have not played with a Schick arm but the pictures do not look promising. 
The Reed arm is intriguing to say the least and I would love to get to play with one. They look more expensive than 2K though. You never want to buy a used arm site unseen. They are too easy to damage. Just letting an arm sit out uncovered is enough to permanently screw up the bearings. 
Chakster, 18 gms is up there. I use my Koetsu in an arm with an effective mass of 19 gms and the Koetsu is about as stiff as they get. 18 gms might be good for something like the Air Tight cartridges. Lyra's and Clearaudio's would get into trouble. The Ortofon Anna Diamond would work nicely. 
rickraymond, that is correct you want a higher effective mass arm for cartridges with lower compliance. However, there is no typical 12" arm. The SME V-12 has an effective mass of 12 grams and the Kuzma 4 Point 11 16 grams. I am sure there are 12" arms with effective masses over 20 grams. The Sorane certainly looks like a high mass arm but numbers speak louder than looks. Never make assumptions. Assumptions are the mother of all f--- ups.

Wow, everyone's on a roll here, chakster is on the money and matt's
suggestion I think is also excellent. The Jelco would work for you but the SME is better. The Sorane is a wild card. Looking at pictures of it my instinct says no. It has a very complicated structure. I do not like removable head shells that create additional contact points and it looks very high mass. It is far easier to add weight to a tonearm than it is to remove weight.
