Does Every Track Sound Great on Your System?

Every song should sound as good as the quality of the recording allows. Meaning a poorly recorded album will sound as good as it can but it will never equal the sound of a high quality recorded one. To try to achieve similar results from poorly and well recorded albums would be like chasing the dragon.

Try a Charter Oaks PEQ-1. The worst recordings can be markedly improved, the best, maybe not so much if at all. 

Agreed, in worst case scenarios, I use my Schiit loki max and it does a great job on poorly recorded albums.

IF your system is capable of sounding great on some tracks, bass/mids/highs and not others, it’s the fault of the recording, not your system.

musicians, placement of musicians in a space, specific mics used for individual instruments/voices, proper levels for original recording, all the mess of great/good/bad decisions by the engineers post recording, you are listening to the result of that mixed bag.

When it's great, my friend and I often look at each other and say "these guys knew what they were doing".

I don’t try to adjust anything to improve the track, EXCEPT, I love remote balance

to correct/improve imaging that is there but a bit off for who knows what reason. The more revealing your system becomes, you more readily hear a slight imbalance. A slight tweak of balance can make a surprising amount of improvement, not just the centered singer, but all players across the width of the stage are more distinct, sound and location.

And if you need to improve well recorded albums, you need to improve your listening room and system first.
