I am not going to sugar coat this.
I have spent time on the recording side, the live performance side, and home system side of music. I was asked by my brother to apply my skills and knowledge as an ex aerospace/defense engineer to the recording/playback issue you are describing.
It turns out making a great recording is usually not an accident, but making exceptional recordings is rare and usually is just luck. However, there are a few recording engineers who know at least some of the secrets. The big secret is "high performance cabling". If you want to push the limits even farther then the connectors on the equipment needs to be upgraded and some equippment may require recapping. Endorsement is a big issue on the recording and performance side so I won't tell you who I have done work for.
But just like in the Audiophile world the question is what makes for a "exceptional cable" and which cables sound the best. It boils down to what is good enough for the job.
In my cable design studies I have attempted to reduce the difference between a live performance and a recording of that performance. My lab was a recording/playback room with typical "Rock Band" equipment and I can barely play an instrument and off to the side I had a electronics lab with fabrication capibilities. When accuracy and noise control are pushed to the limits of available materials, previously unheard detail and emotion are uncovered in the music and it is like you have never heard the recording before.
I did find something I did not expect in my studies. Some peoples brains reject what others call an improvement. The people who's brains accept the increase in performance appear to be addicted to the sound created. I am one of those people. In case you were wondering my design work only looses a cable shoot out on price, The competetion will reduce the price until they sell their cable.
There is one problem with my cable designs, it will uncover every inadequacy (or lowest performance item) in a system and I expect the owner to blame me. Therefore I highly suggest only one brand of cable in a system, mixing causes problems. Ray Seda wrote a review in two articles describing this problem of mixing cables.
