I have since September 2014, the first purchased at a famous Parisian (Suresnes) studio.

I tried about twenty and I just make up my mind for this family. I did not know this family and came across it by chance in reference after buying a Kenwood M-2 that I have to fix it.

Especially when we superimpose 3 A special feature is that there is a double set of knobs for adjusting the level of two separate sets of speakers (not used simultaneously).

The cost of this architecture using many transistors probably precipitate abandonment of this great solution! It also uses the technology ZDR (different from a reaction against classical)

I do it again and just make the election (3 amps in one month and the Bay LBC) I will shortly pictures of animals
