i think what might be more illustrative is to look at the Vandersteen amplifiers for potential clues… The M7 is all out hybrid tube and SS outputs with a SE quasi ciirclotron typology with liquid cooling for perfect bias, no emiter resistors….built in HRS style isolation in a novel hanging truss…. the list is longer….
The ( much ) more affordable M5’s are all SS but have similar architecture. I believe the first preamp will be intended to mate w M5 level gear. I expect Richard will build a mate for the M7…..eventually…. i am in line and will evaluate it in 2 systems using Vandersteen amps and speakers. Finally for US audio shows, Vandy often pairs w ARC and many Vandy dealers carry both…. customer choice will be enhanced in most cases…how wonderful
best to all
