ceramic drivers sound more pleasant with tubes. i know one who uses antique sound lab asl hurricane monoblocks to drive the coltrane alto. 100 tube watts minimum. tubes are more live. for solid state i would recommend redwineaudio 70.2 / spectron musician monos or accuphase e-450 / gamut 150 / Pathos logos integrated. For digital Weiss DAC2 (=minerva but cheaper) or berkley alpha.
good luck
