Cable Guy has only made two posts and he sounds like he's trying to write in the style of a typical reviewer, which sets all our teeth on edge. Without knowing what other mics he's familiar with, it's very hard to trust sweeping recommendations like this.
His comment about Larry and J.P. at ADK being passionate about sound is very true, but sweeping generalizations about the A6 (without any direct comparisons) makes it difficult to validate the conclusions he reached. Let's compare it to the Joe Meeks JM 47, or the MXL 960, or the Studio Projects T3, or some of the other tube mics in that price range.
That would help - a lot !!
