Best value: Excellent

I use this amp since 1990.
This is a great amp (the sound is superb).
The build quality is very good.
The only small complaint was about her look too simple (no LED ...).
I happened to take it apart to see what was in the "flop", the size of the radiator is impressive!
I bought this amp around 2000 Francs, I think in retrospect it was an excellent price / quality ratio.
