I can't afford the many tube amps, preamps and including solid state or FET amps the fortunate members here have and I ENVY all of you for having awesome amps and preamps. I'm happy to have my CARVER/SUNFIRE AMPS since I am a carver fan. My future plan is to get more tube amps that I would hang on for life. I am currently happy with my paxthon integrated tube amp which matches well with my ess heil 1d loudspeaker and grant fidelity cd 427 tube player. I agree with the tube people. I didn't know how clean tubes are till I bought me one.
