Hi,

Officially it is Exclusive M4a made by Pioneer´s special department and distribution was limited to Japan. This M4a(1981) model is an updated version M4(1974). Pure 50w class A, so it is good room heater, inside only high quality capasitor, resistor, special edition component ,140micro thickness copper foil glass epoxy group board and they even made hi-mass powercord for this amp. Built like tank and still everything works like glory days of this amp.  I really like how it sounds, smooth, powerful and it fits well with Luxman´s tube preamp.



There is lot of information

Hi,

I have recapped(Luxman cl-40) nearly every old ones-->Rubycon nos, Audio Notes Kasei ect. and also new nos tubes by Siemens ecc83, Siemens ecc85 , Brimary 12BH7, Rca 12BH7A black plate, Telefunken ecc82 and I can say It is very musical 3-d sound, so I you are lookin for Luxman´s tube amp just go for it. Excellent sound quality, don´t know that one by Tim de Paravicini, but his amps have very high reputation.
