There's rarely a correlation between good sound and what sells anyway. And it's actually harder to separate the production qualities from the rest once the performance quality is top notch - because it fortunately tends to overshadow everything else.

Many years ago I produced and mixed a 7 x platinum selling project on a defective and noisy Behringer mixer and low quality AD/DA Audiowerk sound cards. Still sounded like crap though, so while it certainly qualifies as "worst gear" it didn't qualify in the "best production" department ;-)
