I’ve heard The Angstrom el 34 push pull amplifier and the Jadis el 34 (Not the KT 120 based model mono blocks). No question about both of these brands are exceptionally good sounding, very natural. You re getting into a much higher price range and I’m not sure if there’s a budget ceiling. By comparison the very well made Quicksilver is far more affordable and I suspect quite good sounding utilizing KT 150s. There are numerous good tube amplifier possibilities. I have heard flattering comments in regard to the KR Kronzilla amplifier .
