I recently installed the OSD ISS6 in my home to manage speakers across different rooms, and it’s been a game-changer. The build feels sturdy—no flimsy plastic here—and the metal casing gives it a premium feel.

Wiring was straightforward once I figured out the screw-down compression fittings (not the finger plungers shown in the manual). Pro tip: use a precision screwdriver for the terminals. I ran 14-gauge wire, and the connections are rock-solid.

The impedance protection is a lifesaver. I tested it with three pairs of speakers, and my amp stayed cool even after hours of use. Sound quality? No drop-off, even with multiple zones active. It’s perfect for my backyard parties—I can toggle between the patio, garage, and pool area without missing a beat.

One gripe: the wire clamps are tight. Stripping wires thin enough to fit is fiddly, but it’s a one-time hassle. For the price and performance, this selector punches above its weight.
