When I want science, I look in the mirror. I have been making a living in the science field for over a decade.
Back to the topic at hand for the OP.
Spend your $ on room treatments, an area guaranteed to give you measured improvements. Spending $ on cables won't give you a measurable difference, much less an audible difference.
Now, a question for witchdoctor: Are you suggesting that cables would be a better investment than room treatments and provide more of an improvement than room treatments?
Do you suppose that Hollywood and that various sound engineers spend their money on room treatments or on fancy cables? Almost certainly, your music was recorded and mastered on equipment with general run of the mill cabling, so why would fancy cables at playback make a difference if the actual recording didn't have the same or better cables?
If you want GOOD QUALITY (broadcast quality) cables at a FAIR (not cheap) price, then look no further than BJC
