Bought, sold, re-bought, re-sold Lamm LL2 Deluxe.
Bought, sold, re-bought Shunyata Anaconda power cords.
Bought, sold, re-bought, re-sold, re-bought Purist Audio Venustas interconnects.
That's it really.
Might one day re-buy a Pass Labs XA-30.5 (although I only owned it long enough for an audition before I bought Pass Labs XA-60.5...which I sold).
