Marking Audio Analogue's 20th birthday, the £2999 Puccini Anniversary is described as a 'zero feedback integrated amplifier' (although it must still use some limited local feedback to help keep things on an even keel in its various stages). This is a dual-mono design, its symmetry not only obvious when you pop open the lid, but also evident in the layout of the rear panel, with inputs/outputs for left and right channels physically separated and mirror-imaged.
