Quad 306 in nice condition. Jolida Fusion DAC Preamp also available. 250 each or 450 for both. Can demo. Also have Quad ESLs. One is fine, the other hums. I've rebuilt ESL 63s in the past but my hearing is no longer good enough to justify messing with these. Not sure if it's a circuit board or the panel. Boards are easy, panels a serious pain.
