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

Which version of the JLTi do you have? My version is mk4 with manufacturer mod (optional loading for MM up to 100k if needed). Now mk5B available.

I wouldn’t even look for a tube phono stages. In my opinion phono stage must be Solid State and JLTi is excellent, if you have a very old one you’d better look for the latest JLTi.

Next to the JLTi on my rack I have Gold Note PH10 with PSU10 (MM/MC, WLM Phonata Reference (MM/MC), 47Labs Phono Cube (MC only).

I think very few people on audiogon are familiar with JLTi, but it's a great bargain and very interesting design, it's not a conventional phono stage!

I have the 4th version. I have loading plugs but don't use them anymore. I talked to Joe about sending it to him for updates. Very reasonable to get that done. That will probably be the path I take.
I remember the shootout with the JLTi and other high price preamps. It was preferred by most and Jay Kaufman became the US distributor. I bought mine right after that. Yes it does sound good. I'm just looking for now. I'm trying to fight off the urge to buy something. LoL. You understand, dontcha? (-:

For sure, I have the same disease. 
Try Gold Note PH-10, I bought it after JLTi mk4

I also have the  Herron VTPH-2A and don't use the loading plugs with my Zu Denon DL-103.  They are out of production, so your only option now is to find a used one.
