Quality system, make poor recordings sound better?

My experience mirrors OP, Almarg ... In a high resolution system, one can hear the flaws in poor recordings. For me, the most obvious is compression, brightness and thinness.

Most Bruce Springsteen, Heart (Heart, Bad Animals ...), Liz Phair, Garbage V2.0 ...

The Dreamboat Annie masters were excellent. Nautilus did what I think was the best pressing of that album. Still my go-to for demoing Rock bass resolution(the synth & drum/Fender bass doubling on Magic Man)

How about the CD? I'll pick one up if also excellent.

Knight- Dreamboat Annie on Mushroom records, which I think is a KenDun master is actually a great sounding record.

I have most Heart but no Dreamboat Annie :-) There are hi-res releases now so quality has improved?? Concerts in Blu_Ray is very good.
