VDH Colibri XPP. Best Load impedance?

I have used the Colibri XPP a few years back with the Pass Xono phono, and settled on 200 Ohm loading. Since that was quite a while ago, I couldn’t remember whether I tried it with 47K Ohm though!

I agree with Geoch. I don’t think the internal resistance of the Colibri XPP can be any where near 500 Ohm. While the resistance of platinum maybe a little higher than copper, it can’t be that much higher.

I had, and still have, the 0.22mv version of the XPP, and come to think about it, I believe the 200ohm loading I was using was recommend by VDH, by the hand writing in the box.
