They were recommended to me by the late Brooks Berdan. He included an evaluation of the design and theory behind Hi-Fi products when deciding what to sell in his shop, and was a long-time Eminent Technology Air-Bearing Arm dealer. He installed that unique arm on first the Oracle table, and later the VPI HW-19. Brooks found the push-pull design of the Eminent Technology Linear Field Transducer---the LFT (magnets on both sides of the LFT’s Mylar driver) inherently superior to the single-ended Magnepan magnetic-planar driver, and it’s vapor-deposited conductor superior to the Maggie wire conductors, being of far lower mass. They have superior low-level resolution and transparency (Maggies need to be cranked up pretty good to overcome the "Maggie mist"), as well as dynamics, and play better at low volume than do Maggies. They play louder with less power, too (regardless of the relative sensitivity specs), and have a more extended low end (except for the huge 20.7). But that Maggie ribbon tweeter is sure nice! I have both LFT's and Maggies (as well as Quads), but for $2500 it's no contest imo. Maybe if ET had more dealers, and/or got more reviews, the LFT-8b would have a higher profile. People don't know what they're missing!
