Sorry I didn’t see this thread earlier… Curious what you decided.
I’ve had various Eminent Tech models since the mid 1990s with a number of other large planars starting in 1980. My 1st pair were LFT-VIs which I orignally ran with a very modified (think crazily-rebuilt) Counterpoint SA-12. That sounded ok but I got much more liveness and dynamic jump with SA-20s and later those rebuilt into NP-220s.
After a move and storing the LFT-VI’s in 2006 while we got settled, I got a steal on a pair of LFT-VIIIAs to use as temporary speakers. I again started out with the SA-12, but soon moved to a pair of the B&0 Icepower -based Class D amps from www.tweakaudio.com with his custom build and mods. Going from a roughly 110 wpc amp to monobocks that put roughly 700 wpc was ear-opening. I didn’t feel let down in any way by those amps through 2011.
I transitioned to a pair of the Hypex NCore NC-400s again with tweakaudio.com’s implementation tweaks and while they on paper had roughly 1/2 the power, they sounded a bit more powerful… what gives? Dunno, never worried about it too much.
Besides implementation tweaks suggested by Ric Schultz from www.tweakaudio.com, another thing that pushed the NC-400s above the tweakaudio ASP1000’s was my first PS Audio P10 Regenerator. I could not have lived with those amps long-term without those implementation tweaks and that P10.
Late 2017 I moved to a BHK-250 powering the LFT-VIIIAs with a nice jump in SQ overall… of course $800 or so DIY’d amps versus the $7,500 list BHK-250, I expected that and heard it in spades.
I also now have a 2nd setup running with LFT-IV’s driven by another BHK-250. Based on my experience with these three Eminent Tech models, while they will play with the minimum-recommended power, they really come alive with 5x-10x more. I’d get BHK-300s for each system if I could both afford them AND for the smaller setup, actually had a place to put the 3rd chassis of that size (P15 + BHK-250 currently).
So again, curious on what you decided and how you felt about it. AND how you are liking the LFT-VIIIBs. I know that while I’ll be doing various configuration, mechanical and crossover tweaks to my various ET speakers, I believe these are my last-buy speakers.

P.S. I’ve written a bit about my ET and overall planar speaker experiences on the Planar Asylum on AA and more recently on the Audiogon forums here:
