One of the all time great SS amps, Gives a lifelike stereo image combined with a natural timbre to mid/lows,extended highs with no grain or harshness at any volume.Incredible detail,dynamics for its price point. I have also owned the X350 and this smaller newer amp sounds much better-more refined and dynamic with more detail. Has original packaging,UK supplied 240v,pics on request. £2295 X2.5 for sale at £1450 Thanks for looking
