I just bought a pair of these. They sound great with rock/blues, such as BBKing:
However, when I play this classical piano piece (which is mainly what I listen to--reviewing performances for reference for my daughter's piano practice), the bass is quite muddy:
Note that the Beethoven Moonlight mvmt. 1 is very hard to find a good recording of, since it must be played very softly. This particular recording is fairly good. When I play the downloaded .mp3 through my Cowan + Koss Porta-Pro headphones, the bass notes are not muddied and the midrange melody is clearer and stands out a little better.
I feel like A2's have some mid bass peaking, which makes the midrange in general not stand out. So for this recording of this piece, it might be particularly pathological, resulting in the melody being barely audible. But it is clear to me that the headphones reveal that the recording is satisfactory, and some loss of clarity is resulting from the A2's.
The following recording of Moonlight is a bit better:
On this one at least the notes are distinct, but there's still a boxiness to the bass.
This one is a wreck, with the lower G#s on the right hand making a boxy resonance every time she hits them. Unlistenable:
I'm not sure what I'm going to do with these things. I'm contemplating trying to test the flatness of the built-in amp response to see if they are equalized to have a bass peak, or if it is the cabinet acoustics.
Considering the price, I guess they are still impressive speakers. But they are seriously questionable for classical piano. I guess I'm slightly disappointed. It will also probably make me seriously psychoacoustically confused when I listen to the Dali, since they have a not particularly loud, but very clean and decently extended bass.
