Pass XP-17 and Hana ML loading question

Guys anyone here has any experience with the Pass XP-17 settings for Hana ML?

I just switched form Pass XP-15 to 17 and its totally different animal. 

Just to compare them both with the gain set at 66db and loading 333ohm they act completely different, while 15 gets maximum bottom and fantastic detail 17 sounds great at the top and the midrange but bottom needs improvement.  Would anyone run 47K ohm?

Have you tried a 47K ohm load with any other typical LOMC cartridge, ever, with either of the two Pass phono stages?  What was the result?  Thx.  Also, can you define "terrible"?  Do you mean that the treble was rolled off or missing, as you mentioned earlier?

No, unfortunately I own only one MC cartridge Hana ML , my other cartridge is MM Ortofon 2M Black   

And what I meant by saying "terrible" was, sporrans and mid got clipped about 30%  while bass got big but hollow and muddy no definition at al just slams of senseless sonic boom,  and on top of that when record ended and I raised arm I heard harmonics between speakers and cartridge. I went bac to 1k setting and now over 4th weekend I'll experiment with all settings I have between 500 ohms and 1k to see if there is anything else I can squeeze out of the system.

One remote possibility: when you set load at 47K, the two channels are out of phase with each other. That would have to be due to a glitch in the internal wiring of that resistor, since other loads are at least functional. I would consider sending the XP17 to Pass for inspection. If there’s some other problem, they’ll find that, too. Because believe me, there is a problem somewhere.

@ssg308 Check your phono cartridge wiring to make sure the connections are right. If you got one channel backwards it would sound exactly like this!

Which is what I said, too. But it can’t be at the cartridge because he reports relatively good results with all other choices of load R. Which is why I suggested there may be a phase error incurred in relation to wiring of the load selector switch, when he sets load to 47K. Or something like that is reversing phase in one channel, only when 47K is selected.
