Design
The circuit is a fully balanced Complimentary Single Stagger Circuit (CSSC) topology, paired with Luxman's OD-β (Optimized Dual NFB) feedback system. The power supply sits in an isolated chassis with an 800 VA EI transformer and four custom 22,000μF filter capacitors. The layout keeps the power components away from the signal path. The chassis stands on a 5-point grounded FRP base with a box-isolation structure to control vibration. Inputs are balanced and unbalanced. Speaker outputs are original banana terminals, large 3-way terminals, and a Speakon connector, which was a first for a domestic Japanese amplifier. Throughout the amp you'll find high-purity 6N cables, copper-styrene capacitors, non-magnetic resistors, and copper bus bars. The front panel has a large power display meter and a solid aluminum panel with a special peer surface finish. There is a custom AC inlet with a line phase sensor. Connect the amp to a compatible control amplifier and it can be turned on and off remotely.
Context
At release, the B-1000f was Luxman's top monoblock power amplifier. It was the high point of the company's solid-state amplifier development.
