Lamm phono stage LP2.1 Deluxe with low output ZYX MC cart


Does anyone have experience with using the Lamm phono stage with a low output MC cart with .25mV output? I will be using the Lamm LL2.1 Deluxe preamp. Some reviews caution using a MC with such low output, while other reviewers seem to suggest no problems. I would rather not get a SUT. 

Thoughts?

This is not extremely low output, shouldn't be a problem for a LOMC phono stage. Owned a few ZYX carts and it was fine. A dedicated ZYX active headamp improved the sound, look for ZYX CPP-1 mkII pre-preamp instead of a SUT. 
Zyx can be loaded or unloaded from 100 Ohm to 47 000 Ohm, the manufacturer recommend more than 100 Ohm and it’s up to the owner (depends on the phono stage). Thread about cartridge loading getting hot.

The goal of the special ZYX headamp (CPP-1) is unique load resistors made by ZYX of the same copper wire just like the cartridge coil (if you have copper coil). This is very interesting device, not like a typical headamp or SUT, completely different. My ZYX CPP-1 mk2 has input impedance 125 Ohm as i can see in the manual. I’ve been using not only ZYX cartridges with it (Airy III and Premium 4D) but many other cartridges with great results.



What load do you think is best?

It is interesting question.
If your phono stage has a built-in (1:10) SUT then i can tell you that i have similar phono stage from another manufacturer and it was OK with ZYX LOMC cartridges.

But the ZYX CPP-1 pre-preamp i have mentioned was better and much more impressive for the sound of my ex ZYX cartridges. ZYX CPP-1 Headamp is active device (battery powered) and connected to MM phono input.

With different MC phono stages (with optional loading like my modified JLTi or stock Gold Note PH-10) i never use 100 Ohm with MC cartridges, mostly 500, 1000 or 10 000 Ohm.

However this is personal preferences and system dependent.
