A sh$tty recording is going to produce sh$tty sound. A good recording with a crappy dac and you will get crappy sound. Put a good quality power cord or interconnect on a crappy dac is like putting lipstick on a pig. A good dac will benefit from good cables to get the best SQ out of it.
I also agree that a lot of old rock recordings have little bass. Blues and jazz recordings didn’t have this issue.
