My brother is keeping the Gryphon open I have 2+ audio systems.
the LTA will be going with a Rebuilt older Goldman amplifier that is exceptional rebuilt 3 years ago ,got a sweet deal , I heard the amp already from our local audio club . I listened to it last night the $$ was the only sticking point ,paid under $10 k new $30k+ 2012, 220 v transformer replaced to 120v also.
the LTA preamp sounds Great with it , maybe even better then the gryphon Diablo .the deal was not confirmed until this morning , for a change I get the bargain !!
I have not compared then side by side . I still may buy the Gryphon this summer though from him . $$ is always the deciding factor never enough $$
