Used to be rare LFD Signature mains cable. My experience encouraged Gene Rubin to start carrying them so now not so hard to find. This brought my LFD integrated to life when I thought it already had a life. I have more than I need now and I'm selling extra misc. audio gear to pay for my old Beemer airhead winter restoration. One of the standout ac cables I've owned and I've owned an embarrassing number of them. $400 new. $250 from me includes PayPal and shipping in lower 48.
