Pass XP-17 and Hana ML loading question

 Ok I find it weird at list, I will work with that again, how I have more reasons than ever since I got the Unami Red and I will be comparing it with the ML on the same preamp. Let me know what you think about the ML sound at the 47K load, it seam to me like distortion, overload of bass with the fuzzy bluer in low mis range frequencies I mean around 1KHz. When I drop the load on my ML down to 1KOhm all goes great also all loads 1k and below works great. Gain I have set up at 67db 

@ssg308 When the cartridge generates RFI via the process I previously outlined, it often causes the input of the phono section to make distortion. That distortion is interpreted by the ear as brightness.

If you take any LOMC cartridge and run a square wave through it, you'll see that the square wave is passed by the cartridge perfectly, even at 10KHz. Putting a load across the cartridge (in parallel) has no effect on the squareness of the squarewave. If it were really rolling off the high end in some manner you'd see rounding of the squarewave.

So we know the resistor isn't affecting the cartridge to any great degree. The phono section is another matter as previously outlined. So yes, its very possible the 'Problem might be isolated to the specific gear' you're using.

@atmasphere that is my fear that my preamp my tone arm and cartridge all together are problematic, the least I suspect would be Pass but its possible XP17 don't like something in the configuration. I was thinking about secondary turntable, i didn't yet figure out what its gonna be but RP4 or 6 sounds good to me. Do you have any expirience with ML or Red in specific tone arms ? what works the best ?

@ssg308 I have teh ML in a Technics SL1200G arm at the moment and it works fine. Plug and play with my preamp; no need to mess with loading. One of my employees has the ML in a Triplanar and it works fine in that too.

@atmasphere I'm running VPI with 10.5 arm 

I owned the Pass XP-15 for many years and have been enjoying the XP-27 for several. I dont find the difference between 15 and the 27 to manifest through different loading.  The 27 sounds different (and a little better) at all settings.  Like Lewn, I have never heard a big difference between 100 ohm and 47 kohm loads on LOMC carts. Like ssg308 reports, big differences in character can be discerned with different gain settings.  My conclusions are that the Pass phono preamps can handle RFI generated by LOMC quite nicely.  

Hoping that ssg308 enjoys the Unami Red.
