Sansui AU-555A

Stare buna de functionare,interior original. Estetic unele neajunsuri vezi poze.
Pretul a crescut un pic pentru ca se dovedeste a fi un "muzician" extraordinar. Pe masura ce il ascult pe B&W-urile din anunturi u prea imi mai vine sa ma despart de el.

The AU-555A offers tone quality very nearly on a par with Sansui's 120 watt top-of-the-line AU-999. in fact, performance generally is quite comparable to that of much larger units despite the AU-555A's compact size. A triple tone control circuit has also been added to achieve new standards in trully accurate sound. In addition, there has been a widening of the power bandwidth to from 20 to 40,000 Hz, and the unit now is housed in a handsome walnut cabinet. Versatility hasn't been neglected, either. The new AU-555A features two speaker switches, independently usable preamplifier and power amplifier sections, five outputs and seven inputs. Add all those assets together and you begin to appreciate what Sansui means by "improved". And what the AU-555A can mean you.
