Zanden Audio 8120 Amplifier (Demo)

Stereo amplifier sporting four KT-120 output tubes and delivering 100 watts per channel. This is a topology that delivers the fluidity and dynamic integrity that mark out the better tube designs, combined with enough power to handle real-world loudspeaker loads. And the 8120 is a Zanden amplifier, too: its cuboid form factor, and frosted acrylic front and rear panels, are both understated and ineffably stylish
