+1 for the Gryphon Diablo 300 to the owners of them https://ibb.co/Px6dd9W, it would have to be something very special that I’ve yet to see/hear to top them.

@mickeyb - Jeff Rowland daemon is interesting.by specs alone its a monster
@georgehifi - yes have always heard good things about gryphon diablo 300, it can be in the league in terms of power but not sure whether in refinement
@alucard19 @tms0425 i do not think boulder 866 and vinnie rossi are in the same league but definitely good in their segment
@pokey77  t+a is definitely interesting and worth considering
