loading impedance

I have a zyx r1000 cartridge, per the manufacture's web page, the recommended load is >100 ohms ( I would think there should be a exact # that the phono section should be set to). The preamp that I have is adjustable (with some effort). What should the impedance be set in the phono section? I have heard some complicated methods of checking impedance of cartridge etc. How does it affect sonic characteristics if I were to change from a 600ohm to 100ohm resister?

Sean and Thomas,

Thanks for the tips. I did the impedance settings when my Z1000 was brand new. Out of laziness, I didn't fuss with the Ono's settings. For a couple of days now, I have tried 47kohms (a bit too bright in my system) and 1000ohms (seems so far to offer what Thomas had mentioend in his post without the brightness.)

Eralff, if your cartridge is a new one, waiting a bit for the final impedance decision may be necessary. Mine is about 100 hrs. old. In another 50-or-so hrs. I'll give 47k another go.

Best regards.

Eralff,

I own this cartridge. It's on a JMW 12.5 arm on a VPI TNT Mk. 5. I use the Pass Aleph Ono phonopre.

What worked best for me were loads between 249 and 475 (Ono switch sets). I finally settled for 322.03. These are by no means the standard, it's a matter of long trial and error but, in the end, it pays off.

Best regards.
