Beautiful amplifier and tuner of the great Japanese brand Nikko. I am a great fan of this brand as a former high end retailer because of the constant use of very beautiful and precious components which guarantees durability and a good quality of sound. Beautiful wooden casing and a beautiful layout. What still amazes me every time is the number of possibilities this amplifier offers. Of course it has a phono input, and not 1 but 2!! and of course a tape and aux input, but you can also connect 2 pairs of speakers. What is also special of this category of amplifiers is that this has a preamp output and an output amplifier input! Amplifier: Country: Japan.
