You would think, wouldn’t you? In that regard, recent experience has been statistically improbable!I have seen amps and cabs fail on stage, but more frequently I've seen cables crap out. If you're bringing a PA, I'd look at this a little differently. I'd recommend bringing a few spare XLR cables to have on hand for general use... and then you can use one with your DI if it's ever needed (which will probably be just slightly more frequently than never).
