The A2's are great for near field listening (inside 5 feet). I have the A2's w/ the Audioengine D1 DAC. What a pairing! The DAC really smooths out a lot of the bass muddiness. For the muddiness that's left over, I just use the equalizer in iTunes to reduce it. I think the reason so many reviews of the A2's are polarized (either love or hate) is because people try and use them for what they are not intended. All you need to do is look at the speakers and use some common sense. They won't fill a large room with music. They won't rattle your windows with bass. What they do provide is a high-level of musical detail, natural sounding mids, and a good soundstage (albeit, not expansive).
Even in near field with perfect positioning theres better and cheap options, all of which I listed above.
