My 25 yr old Spendor S100's are configured for TRI-wiring and I've been doing so for over a decade! I recall hearing a difference for the better when I 1st went 'tri' over a decade ago but haven't felt the need to experiment in quite some time. Honestly, I'm one of those audiophiles that 'plateaued' a while ago. To me, my rig sounds glorious, so now I concentrate on spending my money on the music.
