Started with tubes, went through some Solid State, now back to mostly tubes. I'm a Packrat, get rid of little, don't upgrade so much as add systems (Bedroom, Basement, Home Theatre, "Listening Room", Living Room, daughter's room = 6 systems)
Pilot (monaural) AF850 in Garrard console (still have in a box somewhere)
Dynaco ST-70 (factory wired, now modified, see below)
McIntosh MA-5100 (still use)
McIntosh MC-240 (girlfriend stole)
Carver ?? (gone, thank god)
Pioneer Elite M-91 (strong & harsh & gone)
Classe CA150 then CA200 (still use)
then the vintage tube bug hit...
Fisher SA-100 (sweet!)
Eico HF-81 (still use)
rebuilt my ST-70 from high school with Alan Kimmel/Welborne mod (still use)
Bottlehead Paramour 2A3 (in process)
looking for a modern small tube amp, but haven't fallen in love with any yet (Jadis? Manley? VTL?)
I spend a lot more on LP's than I do on equipment and have NEVER had a "state of the art" system. But it's certainly easy to revisit my old sound, cuz I still have it somewhere!
