This will be my first experience with XLR interconnects. Previously I have used Tara Labs prisms, Audioquest King Cobras, Chords ... I have a large tupperware-like container full of all kinds of interconnects.
Speaker wires ... my favorites are the Mapleshade Clearview bare terminated, Double Golden Helix Plus (that's a mouthful), they are wonderful, but very stiff and difficult to work with. I have also used Anti-cables, tried to save a few bucks, they are good, but not as good, also very stiff and difficult to work with. I have some old Audioquest Donkey-Dick speaker cables, I used with some Thiel CS3.6s, retired them as they look too industrial. I have rolls of Monoprice 12 gauge.
