Harman Kardon Citation 5.1 High Current Bridgeable 4/3/2 Channel Power Amplifier

Description

I am very pleased to offer this old-school HK Citation high current bridgeable amp.  After testing it with the DefTech BP towers shown (but not part of this auction), I think it's underrated, as it drove these 6-ohm BiPolar 4-driver speakers with ease at about 1/4-1/3 power used of the 100wpc, unbridged.  This is one of the best amps i've ever owned, not quite up to the fully detailed soundstage of a Krell or Bryston, but along with the Carver A-760X (also posted right now), i would say next in line.  Be very careful lifting or moving this unit - due to the 4
separate
power
supplies
it is extraordinarily heavy.
