Fidelity Research 64s vs Jelco SA-750e

Currently I have a Jelco SA-750e (10 inch) arm on a Sota Star Sapphire with a Koetsu Rosewood Signature. This runs to an EAR 834p, Thor TA-1000 pre, Quicksilver v4 monos, and Verity Audio Parsifal Encores. The sound is very good now, but I wonder if I could decrease record/surface noise and increase bass and dynamics with a better tonearm.

Obviously the Fidelity Research 64s is better than the Jelco, but can anyone offer opinions about what kind of differences I might hear and the magnitude of difference, if I change the Jelco for the FR? Trying to decide if it is worth the extra $1300 or so to upgrade.

Thanks everyone!

The 64 is not a 66. Legacy reviews say the 64 is a little lacking in top end detail. The 850 is crystalline clear.

This review is from 2010 and a plain BS in my opinion. The reviewer more concerned about awful SPU cartridges (the reason why he can;t get crystalline clear quality), but the FR tonearm must be used with FR-7fz cartridge and it's mind blowing experience. The reviewer prefer Thomas Schick tonearm which i oaned with various SPU cartridges and it's nothing special. The FR-64s or 64fx are much better tonearms than Thomas Schick handmade arms. And i believe the Koetsu cartrige is much better than SPU. So the reviewers opinion doesn't matter. 

I wouldn't compare Jelco to the Fidelity-Research 64s.

@montaldo The Koetsu should be fine. I run a Deccas in my Jelcos and they sound excellent with no tracking issues.

I obviously agree with chakster about the quality of the FR arms, owning both FR-64s and FR-64fx. And the synergy with the FR-7 series MC's is certainly special, but they're definitely not a must. The FR-64 arms work their magic with a great many other cartridges as well. I only use them with LOMC's, but according to other owners they even work well with MM's with higher compliance. Despite the high effective mass - certainly in the case of the 64s - they turn out to be surprisingly universal.

I haven't heard the Jelco, but based on most reports it doesn't seem to be a serious competitor to either the 64s or 64fx.

It IS total BS.......and lucky it's on my screen and not in printed version or you know where in my body it would be used.....?!
The FR-66S is arguably the BEST match for ALL the SPUs ever made (A style or G style).
