Hi Bubb, I think you are in for a shock as to how much better your system will sound after proper breakin. Like I said my B&W's sounded absolutely terrible for the first 250 hours or so, and then things suddenly clicked. Another thing I noticed: the sound doesn't progressively get better over burn-in. There are days where things can sound worse than the prior day. So don't judge until you get over 250 hours!
The arguments you make about cables are exactly the same arguments that all cable skeptics have made for ages (quality of cable in your house to your outlet, etc). The counter to the last meter of cable mattering is exactly that: it is the final meter before going into your gear. Source equipment, in particular digital equipment including computers, are VERY electrically noisy, and can pollute your entire house's AC circuit with noise. Having an upgraded power cable connected to such equipment will help prevent (not eliminate) the noise that gets fed back into your power circuit which can degrade the power feeding your amp. Likewise, an upgraded power cable feeding your amp will help filter out the AC noise that gets fed into your Diablo's power supply. Also, there is a ton of electromagnetic noise around your gear. Having extra shielding around the "final meter" will ensure this noise doesn't pollute your power entering your gear. Also, any noise introduced before the final meter will be filtered out.
I am not expecting to like all three cables I am testing. Just because they cost more than the cable I'm using currently doesn't mean I will like it better. The point is, different cables sound different. You may very well try one that costs a lot and think that it sounds worse than a lower end cable. What you need to do is find the one that suits your system and tastes - you do not necessarily need to spend a lot. But you absolutely have to try some different cables with your Diablo and B&W's, or you could be severely bottle-necking performance. The thing about most cable skeptics is most have not tried different cables back to back in a controlled test. Once you do, the differences are so obvious, and sometimes the differences can make the sound terrible, even with expensive cables!! You just need to try a few. One last thing: the power cable to digital source equipment can make a larger difference in sound than the power cable to your amp.
