Fidelity Research FR-64 vs. FR-54


In a prior discussion, I had asked about tonearm suggestions for a Luxman PD-441 table that currently has a Denon DA-307 tonearm and Grado The Reference high output cartridge.  Many suggestions were provided.  A Fidelity Research FR-64 was suggested as a simple replacement.  I'm wondering if the FR-54 would also be good, being that it is mentioned in the Luxman manual in the same category as the Denon arm on there now?

Dear @dover : Btw, please tell me what to look to be aware/detect if my amps are slow or not and specific LP tracks ( 5-6 ) where I can detect it. The amps I can have easily to compare are: FM Acoustics and Gryphon.

In the other side why do you think my amps are slow and slow compared against which specific amps?

Thank's in advance, appreciated.

Regards and enjoy the MUSIC not DISTORTIONS,

Dear @dover : At least tell us why those amps are slow ones.

It's pity that a gentleman like you with your knowledge level come and post " something " with no explanation, with no adcvise to, with no real audio target other that spread your bad attitude.

Try to solve it and give your advise here.

This thread is about FR Arms and was usually hacked from our "beloved" Mexican member who lives in his own world (of distortions).
Let’s be honest, his part time knowledge is not enough for today, his inability to connect something to get a better result is well known. His USA tour was not really successful, some are too polite to name it, but a few told me, that Taco man is in reality even worse than at Audiogon.
High End Made in Mexico needs a bit more than distortion monologues which pop up like a broken record.
Enjoy the music and not distortions greetings is the pale result from someone who creates his own truth.
