The LA-150 MKII Signature Edition is the LA-150 MKII plus V-Cap OIMP output capacitors. It also borrows some other internal components from the LA-300ME flagship preamplifier. These new parts upgrade should give the LA-150 MKII Signature Edition very similar texture as Joule Electra's flagship LA-300ME preamp.
The LA-150 MKII SE has nearly identical power supply as the LA-150ME (no longer in production as it was replaced by the LA-300ME), but the gain stage is not quite the same as the LA-150ME. I think the idea was to create a more affordable "best sound for the buck" preamp.
I had the LA-150ME, which I then upgraded to the LA-300ME. Since the LA-150 MKII SE should be close in performance to the LA-150ME I had, it is a fantastic preamp for the price and most likely the best deal in Joule-Electra's preamp line-up.
Best,
