Do sprzedania amplituner nakamichi sr4e wyprodukowany w Japonii na licencji od Nelsona Pass"a. Najmocniejszy z serii SR ( najlepiej brzmiącej z tą technologią). Niesamowite brzmienie z bardzo dużym potencjałem.
Poniżej link z informacją dla osób nie znających tej technologi.
Próbka brzmienia.

Testowałem inne nakamichi z serii Pa TA - sr4E gra najlepiej pod kątem audiofilskim.
Zaciskinoryginalne wymienione na akceptujące banany i grubsze kable. Zaginął przycisk. Stan niższa cena.

Możliwość wysyłki, Najlepiej jednak odsłuchać.
