Marantz PM-78 / überholt / ClassA 2x25W / Remote RC-62

 

Unscheinbarer Vollverstärker von Marantz: Ein Wolf im Schafspelz! Klanglich sehr transparent und trotzdem Marantz' typische Wärme im Klangbild. Impedanzstabil bis unter 2 Ohm. Hohe Ausgangsleistung im AB Betrieb, als Sahnehäubchen auch noch umschaltbar in reinen ClassA Modus: Die klangliche Steigerung ist deutlich zu hören, wenn der Lautsprecher halbwegs Wirkungsgrad besitzt....noch mehr Details, flüssiger & "emotionaler" in der Wiedergabe. Überholt: Alle Elektrolytkondensatoren im Netzteil wurden ersetzt, Neuabgleich und neue Lautsprecherrelais. Fernbedienbar mit marantz RC-62. Phono MM, Klangregler (am besten wegschalten mittels "Direct" Funktion!), 4x Aux, 2x Tape, LS A&B schaltbar. Kopfhörerausgang. 6 Monate Garantie. Guter Zustand.

Testauszug:

"""...the PM-78 bettered my Quads. Now the bass was deeper and at least as controlled as the reference, while the midrange was most certainly a bit more refined and detailed, which was easily heard on e.g. second voices and choruses on the Mary Black CD. Staging was as good as the Quads, and treble was only a little bit brighter. For the first time now I felt like listening to the music, the whole CD long, rather than just taking snatches, zapping from track A to track B and then to track X, wanting to be somewhere else.

So good now was the marriage with the electrostatics that I refrained from firing up my pair of conventional speakers, Rogers LS-1s. I think the PM-78 can drive just about anything, and I can imagine it would mate wonderfully with for instance the small Magnepan speakers...

I must consider the Marantz PM-78 quite a success: it sounds pretty wonderful with source direct engaged, it doesn't cost a lot of money, and yet it offers a mass of features to boot!"""
