Which tonearm should I keep?

The best Arm is FR-64s

Any other suggestions?

Thanks...

Dear Rich121: The Technics 505 IMHO is the best on those tonearms. Its VTA on the fly mechanism is so unique, precise and " user friendly " like no other, the tonearm too is versatile due that you can change the arm wands that have different effective mass to match almost any cartridge and last but not less important is the whole Technics build quality ( specialy bearing . ): first rate. Yes, this is my " cadidate ".

I owned the FR and are good tonearms too but I prefer the Technics that works well with your cartridges.

Regards and enjoy the music.

One consideration is effective mas. Low mass arms run around 5-7 gms, intermediate mass arms such as the SME V, Linn Ittok and Ekos, Rega RB-300 and descendants, etc. run around 10-13 gms and are generally what most modern MCs are designed around.

The Fidelity Research FR-64S is probably the least versatile of the tonearms you have listed. IIRC when Hi Fi Choice tested it back in the 1980s it had an effective mass of around 35 gms, which makes it usable only with very low compliance cartridges unless you have a record flattener or a vacuum platter to flatten all your records. It's still relatively popular for such cartridges so you shouldn't have any problems selling it for a good price.

You don't indicate which other version of the FR-64 you have - the FR-64fx, which is made of aluminum rather than the stainless steel of the FR-64s has an effective mass of around 20 gms, which can be reduced using a lighter headshell (the standard headshell has a mass of around 14 gm). The Hadcock is a low mass arm IIRC and is supposed to be an excellent match for the Music Maker, which makes sense because the two are made by the same manufacturer. The Technics can be low to relatively high mass depending on which armtube you use, so it is probably the most versatile in terms of matching for different cartridges.

Hi Rich. I think that you should first deciid wich
cart you like to keep. Despite the authority of Raul
(I admire the guy immensely) the only cart that is
compatible with the Technics is the Musik Maker.
My personal preference is FR-64 s (to keep) but that
is not an advice. Even despite the fact that all other carts are comp. with FR-64s. BTW there is some kind of luxury in your 'dillema'.

Cheers
