Today's Fresh Catch: Custom McIntosh Audio Cabinets (and a short Duelund Update)

Sunday Afternoon at Jeff's Place

I had my friends Leo, George, Ron, Stephaen (6Moons), my girlfriend Rosalie, and Santos, over for a listening session last Sunday afternoon. First we listened to some interesting grounding loops from Mark Coles (Sablon Audio) that can be used on speaker cables, interconnects, and the Duelund-WRSE connections. Mark says the grounding loops are basically short loops of very fine gauge litz wire, and act as some sort of ‘trap’ for noise on the signal ground plane. You […]

After completing the Duelund-WRSE external crossover […]
