Years ago I ran Reynaud Twins MKII with an Audion 300B amp (great system) and would like to get back to something like that, but with SS.
I can appreciate the desire to achieve this type of sound presentation with transistor components. Much easier said than accomplished.
Tactile palpability, true 3 dimensional soundstage presentation and organic tone quality are true challenges for many SS components despite their own strengths they bring to the table. Your prior Audion 300b will be hard to equal in those critical areas. You described it as "great system " for a very good reason. 😊
Best wishes to you.
