Hi there, I have got a doubt about phase in a XY stereo configuration. I've always heard that it's a very mono compatible configuration. But a technician here in my city always says that we should avoid this configuration, because if the two micros are not exactly matched (And by that he means a factory preset XY configuration only), there are severe phase problems in the high frequencies. Is it true? Sometimes I need to use this configuration better than a semicoincident one, but I have this doubt. Could someone help? Thanks!
