fisher rs z1 digital reference receiver, 2x150 watt

Zeer zelden te koop aangeboden!

Topreceiver van Fisher uit 1990, uit de 'digital reference series'. Beschikt over zowel analoge als digitale ingangen (coaxaal en optisch) met een hele goede DAC converter aan boord.

Betreft het toenmalig paradepaardje van fisher, in niks te vergelijken met de goedkopere sets die ze in die tijd meestalop de markt brachten.

Nieuwprijs in 1990: 1200 dollar (equivalent in 2024: 2400 dollar)

wordt niet verzonden wegens te zwaar! (21 kg)
(betreft de Amerikaans versie maar er zit een ingebouwde transfo in voor 240 V)
