My $.02 on DSD - it is marketing hype in the sense that any new DAC released this year will be ridiculed if it doesn't support DSD - yet there is very little music available in the format. But I do think it sounds excellent. As with any other hi-res material, it's questionable whether a particular recording sounds better because of the extra bandwidth of the format, or just due to superior mastering or some other factor. It's rare to find the same release in multiple formats where you know they are all from the same original... so comparisons are very tricky.
But in the end all I care about is good music - and I'll take music I like in any format. Some of the 2L Records demo tracks in DSD are amazing, as is the Steve Hoffman master of Bob Marley's Legend in plain old boring 16/44.1 format.
