Optimal loading for Dynavector xx2

The output impedance of your cartridge is 6 ohms. You've no doubt run across the "25 times" rule regarding a theoretical optimum load of 25 x the cart impedance = (in your case) 150 ohms. The actual best loading in your system will fall in a range of 50% higher to 50% lower than that optimum point, in otherwords, 75 ohms to 225 ohms.

It's best to start lower, say 100 ohms, and then move up slowly: 120, 140, 160, etc. until the bass tightens up and stops being muddy/boomy (but without thinning out or losing strength) and you'll be at just the right place.

I have the exact same 0.23 mV cartridge and depending on the phono stage in use with it, I highly recommend you set it for 100 ohms loading.

What make and model of phono stage are you planning to use with the DV XX-2 cartridge?

I am using a Michael Yee PF1 phono stage, very versatile in terms of cartridge load settings.

I am not familiar at all with the Michael Yee PF1 phono stage.

Is it tubed based or solid state?

What gain levels does it offer?

You will find that the DV XX-2 cartridge performs best with 68 dB plus gain.
