I just finished an interview with Vitaliy. He had some interesting comments about the A10 and A12. He said this marked a bit of a departure from his typical house sound of being warmer and more musical. Instead, the ADEL technology allowed him to tune more of a reference sound and still retain a very good stereo image and a sonic experience that was not dry and analytical. This was something that interested me a lot, since initial speculation was that the A10 was like the V6S and the A12 like the V8. Talking to him, it seems the philosophy of the whole line however has shifted, with the A10 and A12 being more neutral and reference than V6S and V8. The A10 is supposed to be the more reference (flat) one, suitable for studio use, whereas the A12 is more akin to a live concert experience- a bigger sound with more kick and excitement. I'll have much more tidbits and anecdotes in my full article, but I thought this was relevant to your question so just figured I'd chime in.
