FR64 cartridge suggestions

Been out of the loop for quite a few years due to some 'life' events, with system in storage.

I have been able to pull my system from storage, and last year worked enough overtime to upgrade or purchase new equipment, but I have not upgraded my turntable/tonearm/cartridge yet.

My turntable is a Technics SL1000 MKII which for those not familiar, is the Technics SP10 MKII turntable mounted on a factory plinth.
I have two Technics B-500 bases with an 'E' armwand and 'H' armwand that I don't use.
The tonearm I do use is a Fidelity Research FR64, so I need a low compliance cartridge.
The cartridge I used last is a vintage Fidelity Research FR-1 MK3 F, which needs to be re-tipped, and I will do so once I get a replacement.

The rest of the system includes:

Zesto 1.2 Andros tube phono stage
Zesto 1.5 tube preamp
Quicksilver V4 tube amps (new KT150 version)
Green Mountain Audio Continuum 3 speakers
JL Audio 113 Fathom subwoofers (pair)

Curious what cartridges other high mass tonearm owners are using, especially those who use Fidelity Research FR64/66 tonearms.

Looking for cartridges under $2000 USD at most.. probably should spend half that.

I have over 20K records, so I am very anxious to get this back into service.

Really curious about suggestions and thanks in advance.

nandric , solypsa :

I believe I purchased his last two B-60 clones for my FR 64s’s.... One slides up and down, nice and tight and no side movement... the other, has slight side movement.
Which I could know what needed to be fixed and knew where to take it... Not much for ’intricate’ machine shops here... larger production stuff.

Yes it is a screw...if memory serves (it has been several years since I had mine apart) the very tip of the screw is machined smooth to form a pin that extends into a vertical slot in the inner piston. Maybe I forgot the detail.

Anyway mine is too small allowing movements horizontally when the inner piston travels vertically- as is the case with others as well. So screw needs to be correct length, fit the threaded outer body and fit the inner slot tightly.

Anyone want to make some :)

Solypsa, ''Those damn details'' (grin). My theory was that the

(cut) thread on the screw was the ''guilty party'' but it is ''your

very tip on the screw'' . Aka ''the nose'' on the screw. Considering

the fact that only few complained about its dimensions this

imply that they are not equal. Some are smaller then the other.

This is an huge error for an ''exact replica ''.

Yes it needs to be machined to very exact tolerances...or many extra made and then hand selected for 'fit'.

Another question.....

I have both the FR64 and FR64S

The FR64 has a round disc shaped 'Lateral Balance' weight, which is smaller in size/mass (and different) than the long cylinder shaped Lateral Balance weight used on the FR64S.

Because of this and other differences, does the FR64 have significantly less Effective Mass than the 35 grams of the FR64S?

I have sent the FR64S to Ikeda for rebuild and silver internal wire replacement.
Would the FR64 have near equal performance as the FR64S, but with the ability, if it does have less Effective Mass, to work better with cartridges of slightly higher compliance?
If so, I will have the same rebuild done to it.

I have recently purchased the SoundSmith Sussurro II ( 10μm/mN compliance) and just got back my FR-1 MK3 F from SoundSmith which had ruby cantilever/retip and last week sent them my FR MC201 to have the same done, they are both also 10um/mN compliance.

Would the FR64 be a better match for these cartridges than the FR64S?
More to discover
