Dynaco A-25s rock! Would love a pair of Madisound's modern interpretation of the classic A-25. They look stellar. Had a couple pairs of A-25s, and my first real "audiophile" speakers were the rare A-50s, which ate amp voltage and current like it was going out of style. My Phase Linear 400 ran out of juice driving those things.
Hypex NC400 > Dynaco a match made in heaven.
Dynaco and one other brand whose name escape me ("EPI?") were audiophile speakers that Consumer Reports rated Best Buy, back in the 70s.
PM your address and I'll figure out how to ship these. Maybe an art tube is ideal.
