Mine is the BMC MCCI Signature ULN current injection phono stage. In the end I preferred it over a Simaudio Moon 810LP, Audionet PAM G2 w/ EPS, and ModWright PH9.0X. I don't ever forsee myself wanting a different unit. Current Injection stages work best with very low impedance moving coil cartridges, and I'm using mine with a My Sonic Lab Signature Gold which only has a 1 Ohm internal impedance.
If you have interest in reading on my journey to this stage, here's the thread where I documented it.
