Quite a rare beast and this one is in mint condition. Electrocompaniet AW60 - balanced amplifier, a wonderful tube like sound, powerful and detailed and sounds much better than the 180 brother. A brilliant amp for little money. It is balanced but note the XLR sockets show a pair of links which I used as I listened with RCA connectors. Collection from NR27 or will courier at cost and buyers risk. £525
