You have not been around long , at least 65% of amplifiers are SS
not tube . I owned a Audiostore for a decade, the progression of SS over the last 15 years SS Mosfets ,or bipolar transistors have many vacuum tube attributes in smoothness ,there are many more SS amps then tubes , plus some speakers need high current high SS is to move panels or drivers ,Vacuum tube voltage driven .
look at Vitus Gryphon, Pass labs, Boulder , Ayre, Bryston Krell ,MBL
Luxman,Accuphase Goldman just to name a few and many are Very $$.
