I think that there's a place for a receiver and sound processing to make poor recordings more enjoyable. Whenever I've made a change that I felt was a significant change/upgrade I've found that my favorite albums and songs tend to shift a bit. There's also an aspect of simply becoming more annoyed with poor recordings as a more critical ear is developed from listening to systems with a high SQ.
When I got my Denafrips Ares II DAC a pleasant surprise was that several of my favorite albums that are not great recordings became enjoyable again. I guess it would be fair to describe the DAC as being "musical" in my system.
