I think that it is impossible to assemble one system that will sound great on all recordings. I have developed this theory over several decades. I feel that the "problem" is in the recordings themselves. Their sonic signatures vary from recording to recording due to processes, engineering, mastering, etc. So while one recording may sound a bit bright with some gear/cables, it may sound just perfect with another set of gear/cables. Obviously you can replace the word bright for many other audiophile adjectives in my last sentence.
I recall visiting a gentleman about 8 years ago who had a 4 armed turntable set up in his main system. 4 different arms/cartridges and phono stages. He was able to vary the sound to his taste by using a different cart/arm/stage on any LP. This is what really started to make me realize that my theory had some merit. The same recording could sound stunning on one setup, and just OK on another. Most recordings could be made to sound very, very good, it was just a matter of setting up with the proper cart/arm/phono stage.
