Description from the seller
The Denon PMA-860 is a heavy integrated stereo amplifier, built in Japan (circa 1991–1993). Within the PMA series this model is known for Denon’s 'Optical Class A' circuit, a generous transformer and substantial power reserves. This provides stable drive and enough power to also drive more demanding speakers. The amplifier features a Source Direct switch for a shorter signal path and a built-in phono stage that can be switched between MM and MC.
The unit is sold as a standalone amplifier.
Condition-wise, the amplifier is in nice condition with normal signs of use for its age. The unit has been tested and is working.
