If memory serves JS Audio just have 861 driving DSPs. An inquiry might get them to set up an analog demo though. Dave, if you feel inclined to wander north, I'd be happy to let you hear my soon-to-be 861v8 with Analog Genesis speakers (Stamford, CT).

My Kit: 861v8+ID41, 800v4, UHD722, MD600, MS600, MS200, Oppo BDP-203, Genesis 201, Genesis 350 SE, Genesis S4-8 Sub, BG 520i, VTL MB450 II, Krell Showcase 7, Genesis 928 Subs, Danley DTS10 sub, SVS Ultra 16 subs.
