While you can record a setup with a pair of good quality microphones/binural & recording gear, (like Ron does in his channel) it's never going to be an exact 1:1 representation, and those variations are going to change depending on how you listen or analyze to those recordings, the room they're being recorded in, etc.
The reality however, is that while measurements & graphs are a decent indicator of a products overall quality/potential, you can't rely on them alone, especially when everything about your setup is wildly different from those of the testing conditions, and will vary depending on room size, shape, layout, placement, furniture, treatment, types of wall/flooring, etc.
It's not particularly easy to graph & chart an experience, you can try to explain it with words, but not everyone has the same definitions, understanding or even the vocabulary to explain it effectively. And to top that off, not everyone will experience something in the same way. One persons excitement may be another's horror.
It's something you have to be open to messing around with, & if you have a chance, go visit Danny or talk to someone in your area that is willing to let you visit to try out different cables on their system, and see if your experience changes. And possibly even bring your current system with you since you're more familiar with it's sound, but at a minimum, bring music you like or are most familiar with.
