Part of the fairly rare "1" series, expressly designed for Sony's SACD launch, alongwith the SCD-1 reference player, TA-E1 preamplifier and SS-M9ED loudspeakers.

This bombastic mammoth of 70kg holds 10 pairs of non-magnetic & gold-plated Sony MOS-FETs (2SJ120A & 2SK1530A), Metal Core Modules, a non-magnetic chassis made of 15mm and 10mm aluminium slabs and copper plates, specially designed 4N aluminium foild electrolytic capacitors, a 1,5kVA Torus toroidal trafo housed in a ceramic compound, 30A rectification diodes and a fully balanced circuit and set of input plugs.
Each diecast heatsink block weighs 16kg !

The final stage is, unlike the previous TA-NR1 and its TA-NR10 updated version, setup in Class AB for a better efficiency and (much) less heat problems.

Metal Core Modules are made of an aluminium alloy circuit-board on which circuit patterns are formed with copper and parts are surface-mounted - better conductivity, better heat regulation, minimal track lengths.

To stand the bandwidth required by SACD sources, the Linear Phase Circuit was designed, the schematic of which you can see below.

The production is supposed to have been halted after the first 100 pieces but there should be a bit more than that around the neighborood - rich neighborhoods.
