Can flexible power cables sound good?

Hoping to not provoke the eternal cable debate, I do not see how could I overcome the shortcomings of the 15-25 feet of cheap power cables in my apartment walls (on top of at least 50 feet from the main breaker and meter in the basement) by spending on the last 3-6 feet.
I have other priorities now; when the rest of the setup will be to my satisfaction, I will look for a high power double conversion UPS; only when I’ll have plenty of clean AC, I may try some power cables.

Kimber Kable power cords don’t get much praise but their PC’s are great for the money and extremely flexible. I later moved to WyWires which aren’t bad to maneuver, but definitely not as flexible as the Kimbers.

A number of relatively flexible power chords are good sounding, 
Acrolink, Kondo, Acoustic Revive, some Furutech, Audience, Shunyata, Morrow,... sorry for not mentioning more.
if they sound better than the stiffer ones I do not know.
@inefficient the last 3-6ft you mention are actually the first ones, you start from there. If you continue to board still better.

In that case, consider spending on the *first* 3-6 feet. (Seriously, the nature of AC power makes this conceptualization just as valid.)

Also, you might think about running a dedicated line from your breaker panel to your audio system—clear up your identified shortcomings and a whole lot more. If your panel is really that close (15-25 feet), then this should be very straightforward.

@martin-andersen asked:

So are there really good power cables that are also flexible?

Of course there are. Some of our collective favorite power cords over time have been extremely flexible. I still use several TG SLVR PCs and a couple Michael Wolfe PCs—both very flexible and easy to route (especially the latter). I don’t know most of the PCs recommended in the thread so far, but they seem like contenders.

Finally, I know you have a local dealer (good for you, and all the best to them!) ... but if you don’t find what you need, you could consider getting together with The Cable Company and their lending program. Both for their initial recommendations and for the opportunity to try before you buy.

Have you tried silver coated, aluminum buses?   Only use copper nuts and bolts.
