Luxman M-4000
Luxman M-4000a

(1976 > 1979 > 1981)

"Luxman, following the prestige M-6000, now introduces the M-4000.
The best cost/performance was sought in this unit, utilizing the same engineering concepts employed for the M-6000.
"

Before vanishing in favor of the M-300, the M-4000 saw an updated M-4000a version which sported MOS-FETs, Lux's Duo-Beta scheme, a pair of XLR plugs (as speaker terminals), a better s/n ratio by 2dB and 2 more kilos on the balance.
The M-4000a is a true gem.
