Harmon Kardon Signiture 5.0 (5x1oo)for apx 1000 or less is a sweet sweet amp that will last well beyond the 5 year warranty. Only downside it is not bridgable like the 4 channel Citation amps. Bryston,carver, b&k,adcom,shelborne are all good choices and 'sound'(ie amplify without audible distortion) virtually identical and are rather indistinguisable from one another.
