Balanced connection XLR microphone cables ?

They'll work fine, assuming they are not defective or damaged. However, cables used at live events tend to get stepped on, inadvertently yanked, etc. You'll probably be ok, but if you want to play it completely safe use a multimeter to check for continuity and shorts. Or perhaps the music shop can do that for you.

Thanks Al for your response. They are new(3 ft.long,$10.00 ea.).I won't have have any wear issues. buying my cables from the musicians supply shop seems like a reasonably priced option for the future when I relocate the amp and need longer cables.

I bought a pair of inexpensive balanced mike cables from Guitar Center to tide me over while I ordered some "proper" audiophile interconnects. To my surprise they sounded terrific and only cost me about $60.

Here is a not-so-true story.

I purchased some inexpensive XLR cables from a music store also. Plugged then in, and noticed a horrendous improvement in soundstage, imaging, focus, lower and upper frequency extension...and the tingling in my nose disappeared. I immediately sold all of my equipment. Then I purchased horrendously less expensive equipment. To conclude this tale, I then purchased horrendously expensive interconnects to improve my sound. Now I feel like I accomplished something.

Disclaimer...I'm being silly if you haven't guessed yet.

I'll add a couple of things to my previous post. B&H Photo Video is an excellent place from which to purchase pro-oriented xlr cables, online. I use a pair of Mogami Gold Studio's between my Bryston cdp and my Classe preamp, and I've been pleased with them (although I haven't made any direct comparisons with high-end audiophile-oriented cables).

There was a thread here a few months ago about using inexpensive pro-oriented cables instead of much more expensive audiophile-oriented ones. As might be expected, opinions differed widely.
