If 200 lbs weight and generated heat does not bother you then Plinius Reference is a great amp. One of the best around. A touch better then Spectron in highs and touch worse then Spectron in the bass and slam areas. Midrange, I much prefer Spectron but with Bybee filters only. Without Bybees - if I recall well, both are about the same (except weight and heat)
ARC Ref.3 - no comparison with BAT REX or Joule-Electra LA-300 or VTL 7.5, in my totally subjective opinion. Dry, no life-like presentation which you will need so much combining your tube preamp with transistor amp be it Spectron or Plinius.
All The Best
