Hi Catmansound,
Welcome to the Red Wine Audio Forum - and THANK YOU!
http://redwineaudio.com/components/lilianaLieFePO4 has serious UMPHHHH - especially the custom designed pack that we are using.
That, combined with the 8-FET output stage, delivers serious current, and "DC-Direct" with
no AC/DC conversion. Even higher efficiency speakers will enjoy its super black background, huge dynamics/ soundstage, and natural and engaging sound.
Yes, the Liliana Monoblocks (like our Signature 15) are the first LiFePO4 battery powered component to use a Class A tube input stage (using no dc/dc converters, no transformers, etc.), followed by a Class AB FET output stage - and this gives rise to its one-of-a-kind sound!

I am confident that those who listen to it and compare it to much more costly competition will find it to be an excellent value - just like the Signature 15.
We're building the first few pairs now, and will be able to begin shipping hopefully by the end of next week.
They'll also be at the NY Audio Show!

All the best,
