Technically no, but...if the cable ends aren't very good, then yes. I only use Vanco. Monoprice and Bluejeans(both have links in the header above) have good cables as well. Dynex is not a quality brand...and I don't expect quality out of anything contained with-in a package from them.
You can find plenty for $1000. If you already have 501(the 501 and 601, in my opinion, are the ONLY Bose worth buying), what series are they?
Just keep in mind, Bose DOES NOT WORK with any form of Audyssey. The DSP contained with-in Bose products negates any "auto correct".
