Stereo_phile, It is interesting that your shootout confirmed the traditional concept that you get what you pay for.
When I checked on the prices of the speaker cables, they ranked in descending order:
$4500
$2106
$950
$870
$225
As I had posted admiringly, above, "Your system and the wiring that has already worked for you reads like an audiophile's dream list."
The prices of the IC's in your shootout can be tabulated by someone else, but I suspect they don't come cheap, either.
Down here where the Shakespearean groundlings dwell, I still recommend wiring a system with Reality for its performance, its moderate price, and its home trial policy which lets each listener check for synergy with his/her particular system. (I have never tried the power cords.)
