What defines a good tonearm

I posted:
+++ " It helps that we use a R2R as reference/comparison?, certainly yes ... " +++

I think I was plain wrong, certainly does not helps because a important part of the LP recording process is not on the tape, example: RIAA eq de-emphasis, cutting lathe amplifier added distortions to the process, vinyl pressing and the like.
For we can know what we are loosing through playback LP on an analog rig we need to differentiate between these two 2 stages " after the tape information.

Yes, a R2R give us a picture of what is the sound with out those two stages process where signal is heavy degraded.

So, IMHO that kind of comparison: R2R against LP playback at home is more " academic/retoric " than a useful one tool.

Hello Lewm....I must agree on the air bearing linear arms...they sound funny to me never liked them much...Now the old rabco (when working correctly) and the much newer pioneer's pl l1000a's arm is fabulous...uses a linear motor for arm movement the arm also uses a graphite composite arm tube and dissipates cartridge energy via high mass structure now that was engineering IMMHO

Dear Atmasphere: +++++ " I'm just trying to get the LPs to sound as close to the master as I can. " +++++

well, IMHO the best you can do it is to be nearest to what is on the LP grooves that in the records you produce/produced you know what is what is on the LP grooves and this advantage you have help to fine tunning your system on that regard.

For the ones as me that don't produce records/LP the way to go and critical issue is what Syntax pointed out:
+++ " System and with what kind of records (with Diana Krall for example it is not really easy to rate something)..." ++++

the choice of those recordings ( analog ) is vital for those comparisons, master tapes are useles on this regard.

Now, if what we are testing/under bench are audio items not related to our analog rig the IMHO digital source ( native DVDA/SACD recordings. ) is a great choice and even better than analog master tapes ( R2R ).

Just because I don't have the specs for the friction measurement of a unipivot tonearm, all of a sudden I am a poster child of the subjectivist camp without even a "touch of objectivity"? Thanks for the flattery, Raul. I'm not that ambitious.

In audio, I am an atheist and polygamist. I like choices. If you want to be the high priest of the absolute sound, go right ahead.
