In contrast, Bruce Thigpen---maker of the great alternative to Maggies with his Eminent Technology LFT-8b and 8c loudspeakers---answers the phone himself. He will even advise you on how to upgrade his stock x/o with higher-cost (and presumably sounding) parts. The LFT-8b x/o schematic is available for viewing on the ET website, for those who are technically inclined.
As for grill cloth: Maggies have their cloth stapled onto the MDF speaker frame; the ET LFT-8b and 8c have removable grill frames, for ultimate sound quality listening sessions. The LFT-8b is about the same price as the Magnepan MG1.7i ($3200 including shipping vs. $3000), and imo considerably better sounding (I compared the two). Some prefer the 8b to the Magnepan MG3.7i, at less than half the price.
