Well, like Dean, I can listen to it for hours on end and it's not tiring at all :) I don't have a problem with people not liking the 64, I'm very happy with mine and that's all that matters really but it's sad to think that some potential buyers might be put off by all this stuff about hardness :rolleyes: I guess anyone about to spend £1500+ on a DAC would have the sense to listen and decide for themselves.
