Nothing but tubes. Tubed CDP, Preamp/Phono, SET Mono Blocks . Started with a AR 6B Preamp and Bryston 4B amp then Classe DR25. Then a AR 250 Mk2 Servo [ 32 tubes], Classic 60
Last and staying put are the SET mono blocks. For me after SS then push pull triode I have found my preference in SET amps. Next up if the lottery comes along OTL Joule Electra Rite of Passage.
