Monarchy Audio: High-End at Low Cost

Luxman LuxKit* A3550

* In the 80's Monarchy Audio was the USA kit distributor for Luxman Japan. This model (Luxman A3550) was offered as a kit at a lower price than finished Luxman products. Luxman built a few finished kits for demo/display. The A3550 offered here is such a "factory assembled kit." Monarchy Audio subsequently upgraded these "demo/display amps" with German WIMA and other film caps, bias regulation, and Teflon silver wiring for enhanced performance. A pair of 4-Ohm outputs were also retrofitted to match other  4-ohms speakers (original 8-ohm outputs retained).
