Input on LFD Mistral amplifier, newer versions?

Hello. Just wondering if anyone has heard newer versions of the LFD integrated Mistral amp? They have put out newer versions than the LE, such as the Signature Series. You do not see them much anywhere, and there is no website. What an interesting company. I read the threads here, and they seem positive for the older versions. Thanks for any input.

I have the NCSE and I don't see a need aymore to change my amp. Fully satisfied. The only reason I would ever change is if new speakers would require a much stronger amp (e.g., electrostatic). But so far i haven't had a need
