I owned a pair of A2+2's about five years ago, when I first got into hi-fi. These were my first "better-than-Bose" speakers.
With most of what I have to say about these speakers, you have to keep in mind that I used mass-market calibre receivers and CD players, and I couldn't position the speakers optimally in the room because of practical considerations.
With that disclaimer out of the way, my opinion of the A2+2 is that they had a dark timbre, and not much treble extension. How do they compare with other speakers? I had a pair of Paradigm Mini-monitors at the time for comparison. The A2+2 had a more open midrange than the Paradigm, the Paradigm midrange sounding recessed in comparison. However, I felt that the Paradigm midrange was smoother; the A2+2 midrange sounded rather grainy.
My speaker priorities are tonal balance and vocal reproduction, so my opinion talks about those aspects. I don't highly value soundstaging, imaging, etc. so I don't have much to say on the A2+2's ability in these areas.
Don't think that I'm being harsh on the A2+2. I've never *really* liked any speaker I've owned or heard in a store. That's why I go through about one pair of speakers per year.
Happy listening.
