He has nearly 30 years and not a wrinkle, and certainly better than many amps today. Exellent both in sound quality that is puissance.Il 4 * 75 watts but the real watts.C 75 is a amp semi proffessionnel 70 years has the time or sansui was renowned for his musicality and with good speakers it is an exellent stereo amp with a sound quality with a very large reserves of dynamique.J did it several evenings since I and have no problems even at high volume it can see bronchus pas.On finish it was designed for long facade with its brushed aluminum knobs aluminum massive entries directly etched into the aluminum. With respect to the connection it is also very complete with an output 'Main in' and 'pre out' for the couple to other amplifiers or allow devolved through a preamp or power amp more powerful example . In a word EXELLENT!
I put my highest score and I think it's well deserved!
