I loaded several carts (from Lyra Delos through 3 different Benzs) at 47K through my Pass XP15. Sounded clear and extended, and not "bright" at all. TBH, it sounded almost the same at ~1K vs 47K. Perhaps the Pass is one of those phono stages that's not that sensitive to loading. I now have a Andros Deluxe II, which only goes up to 1000 ohms. I leave it at that. Sounds lovely and better than the Pass, but that's a different discussion.
Running LOMC with MM (47K) loading
This is the way I run my Zyx 4D and my Benz Ebony L before it. I have a JLTi phono preamp which allows me to do this. I have been satisfied with this pre since buying it new. Yet I may be in the market for a new (Different) one. However some I have seen may not offer this ability. One that has great reviews also has the loading and gain all tied together. Not sure about Herron but it may be out of production. Not sure about others.
The question comes with @Atma-sphere comments on loading and circuit stability. He contends that the loading damps (stops) the cartridge cantilever from moving as freely as it was designed (my words) And it is better IF you can run with no loading. But that requires a stable circuit which not all have. Apparently my JLTi has a stable circuit because I have been running LOMC's this way for a 10-15 yrs.
That said, should I require this attribute to my next phono preamp? And might I be better off to send the JLTi to Joe Rasmussen (Allen Wright's partner) for upgrade to Pre and new Power supply?. That will be the cheapest and that is likely to be the step I take. However the question still exists. If the damping is as per Ralph's assessment, it would seem that the stability of the circuit is of greater importance than the ability to have a lot of loading options with unstable circuitry. Another question, Is loading a band aid for a circuit which is not at an optimum? I am not an electronic tech so I am not looking to stir the pot but for my own understanding Thanks
