A Better Bluesound AC Cable?

Bob, in your case the quality of the C7 you chose was not enough to make an impact. In my case, the Wireworld was a transformative upgrade; it was so superior to the stock cable.
The AQ C7 by all accounts is not a very good cable, also the higher end AQ has been discontinued.
Many of these low current 15 gauge C7’s do not equal the performance of a manufacturer’s full line of power cords.

I doubt that your system is limiting. Mine is pretty revealing with Silent Source and Siltech ICs, Audience PC’s. I hear the differences in each cable I swap. I can hear a good from bad C7 when used on the Bluesound.
I think you should try a different cable.

@lowrider57 ,
Thanks for posting. Perhaps my cable wasn’t up to snuff. I’ll check out wireworld-never used them before.
Which one would you recommend?
In any case, my system sounds pretty awesome as it stands.

@gdnrbob, 
I have the Wireworld Mini Aurora C7 for a 30 day audition, $120 for 5 ft. Read my comments above as to why I'm returning it, but it sounds terrific. Realistic, lively, transparent. It really opened up the Bluesound.

@lowrider57 ,
I forgot to ask or didn't see it, but are you using the Bluesound internal DAC or an external DAC?
Bob

Bob, I never tried the internal DAC only because I have a very fine Audio Note plus a High Fidelity S/PDIF cable. 
Sounds wonderful with the Wireworld PC, but pretty dull and uninvolving with the stock.
