I recently purchased the Blue Spark, haven't had the chance to use it on a session yet but plan to very soon, and I will be picking up the EV Cardinal and EV Raven in about a week. I know that EV and Blue worked together on these (at least that's what I've heard rumored from others) so I was wondering what characteristics if at all were paralleled between the Spark and Cardinal. Would I even benefit from having both or does anyone think they'll probably just sound like the same microphone?
