Worst sounding album in your collection

[Smokey]

Worst soundng not in term of music, but rather how it sound and was recorded.

I would have to say worst sounding album in my collection (although like the album) is Big Generator by Yes. First I had it on LP and it sounded so brittle, cold and metalic. And sound was lacking warmth and dynamics.

Couple of years later I bought the CD version, and sound quality was the same if not worst. I don't know if record engineer wanted the album to sound like that or not, but my audio system did not like it.
