I should add that I *do* think the Achordants are a terrifically talented group. And I love groups LIKE them, as well. All 10% of them. I also love hearing recordings that groups like them put out - relatively naked, full of energy, creative, if (one must admit) a bit dorky at times.
But there's nothing wrong with taking your talent in another creative recorded direction, either. And the arguments for "more purity" have traditionally ALWAYS come from the "new kids on the block", or the ones who didn't have a lot of money. It's just a tired argument, and a transparent one. It's funny to watch, over the years, as these groups get more resources and age a bit, how they generally "come around" to the other way of thinking.
