I gained a Proton D540 (2 x 40 W) in 1986 to 4000 francs and since that time, it works perfectly. It is no longer my main system amplifier. He has adapted well to all types of speakers with which I have run (Trent Castle, and Dynaudio Gemini Image QED). It has dual power supplies and large capacities that class into the category of 2 x 80 w. It is very dynamic with musicianship that approaches a NAD 3020i. Associated with remarkable CD player Marantz CD 52 SE, it feeds a pair of speakers in the original kit FOCAL.

This amplifier is very well made, is a safe bet for the occasion and to a very musical.
