Close?
I own the Eaton's bigger brother (Arden) and am powering them with an EVO 300 power amp (Gold Lion KT-88s or Tung-Sol KT-150s). I didn't care much for the stock PL EL34s which are now running in my VTA ST-70 where I care less about critical listening.
In my system, the EVO provides a better experience than the Pass XA30.5 and Conrad Johnson MF2250 that preceded it.
