Optimal loading for Dynavector xx2


Hi - I have just bought a Dynavector xx2 cartridge, loading it with the recommended 30 Ohm setting, but I have read that 40 Ohm is better suited for this cartridge, any recommendation of where is the right setting?

Thanks !

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.
Flg2001: I agree with Xlr8or (based on what you said re: balance toward high frequency) and therefore want to revise my original recommendations.

I would start lower, maybe as low as 40 ohms or sufficiently low to hear "enough-but-poor-quality-bass." "Enough" means loud enough. "Poor quality" means boomy, muddy, bloated. Then add resistance just 10 ohms at a time (because your range from lowest to highest is so small) until the bass tightens up but still maintains good volume level. That's where you want to be.
