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

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. 

You can order the LP2.1 Deluxe with 31dB of MC gain (versus the default of 20dB). This configuration is ideal for cartridges with low (<= 5) internal impedance, which most ZYXs appear to be.

The LP2.1 already has SUTs, internal Jensens I believe with fixed 400 ohm loading. I’d be more concerned about that matching well because doesn’t ZYX like the typical Japanese 100 ohm load?

The ZYX has an internal Impedance: 4.0 Ω (8.0 Ω) Load Impedance: > 100Ω.
The LP2 has set configuration for MM and MC. 47k input impedance which apparently results in nominal value of about 430 ohms load.
Thanks

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.
