Is there a run-in time for Dynavector XX-2?

This specific cart dont know. Normally cart change a lot in the first 25-30 hrs and then settle slower. as new they ar normally excessive bright and edgy. Then smooth out and bass will develop.enjoy how it develops.:-)

Not much changes after 25-50 hours but you'll need to fine tune the VTF and VTA.

Very precise alignment is critical.

Hello

My XX2MKII improved greatly after about 50 hours or so, and continued improving for a while after that. Although Dynavector recommends a 30 ohm load, after I achieved optimal set up, and with a Modwright SWP 9.0 Signature phono stage, the cartridge sounds best at 500-1000 ohms. Others on this forum have also stated this loading works for them. From what I experienced, when your cartridge is not optimally set up, it won't sound good at anything much beyond 30 ohms.

Regards,
Dan

I pretty much agree with Islandmandan, though I'm setting the loading for my XV-1S at 250 ohm. I just got in the mail today a set of load resistors from DB Audio to further dial in the right loading.

Actually, the recommended loading is >30 ohms. So Dan's 500-1000 ohm is well within Dynavector's recommendation. We can't tell you what settings to use on your phono for two reasons.
1) We don't know what load settings your phono preamp offers.
2) We aren't doing the listening, you are.

Try them out and see which one you like best.
