I don't have the same experience as you but I completely agree. Having read
many things around about DSD I am now conviced the other way around, i.e. I
think DSD is worse than PCM at the same bitrate. Here are some iteresting
articles:

Let alone all the processing problems that arise with 1 bit signals.

I think there's also a bit of copyright potection involved. Just the bit
needed to give the marketing depts the illusion that SACD won't be copied.
