Modjeski and Beveridge

Some sources say RM designed the Beveridge direct-drive amplifiers. However, I read an interview with RM where he disclaims the full credit for the amplifiers. On the other hand, IIRC, my own Beveridge amplifiers bear his hand-written initials inside the chassis, dated "1979". Also, I believe RM offers upgrades to the Bev amps.

It would be wonderful if there were a reliable source for direct-drive ESL amplifiers. However, to some degree they would have to be custom-tailored to the speaker they would drive. For example, you could not just take a dd OTL amp designed for Quads and hook it up to Sound Lab, without some changes. I inquired with a Euro-based company, Inoxx, re a direct-drive amp for the Sound Labs. The conversation went in circles. I am not sure they are for real. Ralph has now and then mentioned his interest in such an amplifier, but I can understand his reluctance to go there: Few would sell, and the potential dangers of such an amp (very high voltages) can backfire on the maker in this litigious age we live in.
