Hi Telescope_trade - when u said.
I know B&W recommends a certain type of cable for best match.
Are you sure this comment was not made by a dealer ?
It is an impossible task imo for a manufacturer to say this as they do not know what type of room and gear our speakers will be placed in. All b&w manuals I have read specify the importance of quality cable; not a specific type.
Any other suggestions welcome as well before I run to BB for some Audioquest cables. :o)
Certainly as ZD542 said you can just return the BB speaker wires.
Over the past years I have used good WBT connectors. I purchased various raw wire from speaker wire companies as well as other places and made up the speaker wire myself. This allowed me to experiment and see what wire worked best in my room. Once you have narrowed the type of wire you like ..you can if still desired search out companies that provide that type of wire in a finished product.
I believe however you will have so much fun learning about the effects of the different wire - rather than just swapping out different companies wire that you may stick with your own diy speaker wire. Just a thought.
Hope this helps have fun listening.
