I use a Audioquest Sub-3 XLR-XLR to connect my subwoofer channel on my Cary Cinema 11a to my DD-15. Works well.
subwoofer cables
Looking for recommendations on single ended cables (1.5M) to connect a Mark Levinson 380s pre amp to a Martin Logan Depth subwoofer. The balanced connections on the pre amp are running a pair of Levinson 436 mono blocks, which are hooked up to a pair for Revel Salons I just got.
