I just am picked up a fully restored MX110Z (by Audio Classics) and will use it with a Thorens TD-124/A23 SUT and either Quad ESL 63 (these need servicing first) or Altec Flamenco. I also have a few high efficiency WLM speakers. I am thorn between MC30 and the 225. based on posts on AK and other sites, I think the 225 runs cooler, may be have a bit less noise, better/tigther bass (?) and of course much less space and essentially an "upgrade" of the MC30 with solid state rectification - right? Then mid range is supposedly best with the Mc 30 - i do listen to all sort of music but mostly jazz/vocals/classic rock. i dont seem to identify a clear "winner" although think that with the Altecs the Mc30 may work better - at least differently. Which one you recommend?
