In regard to an inability to discern significant differences in sound between differing wires, my ears, and they definitely are not "golden" indeed have been amazed by the noted improvements. In terms of point to point wiring, at least on my newly acquired Quicksilvers, the sound is extremely captivating and engaging causing one to want to spend more time then is probably good for one's "family peace" listening to all my records and CD's over again. Yes, this is a hobby and changes/improvements often accompany careful improvements to the system. And if you can't hear the "improvements" you can save a lot of money by refraining from "upgrading" but for those "fortunates" that do hear a diffence enjoy your hobby.
