There was two models at the booth, first revision and second revision. It has more bass than the SR7000 on both of them, even if its open back. And slam harder, satisfying way. First revision had a little to much into the low mids, making it less clear and open. The revision two had more balance and clearer sound, it also sounded more controlled. But I would not call them bass heavy headphones, just more than whats neutral but then we can ask what is truly neutral?
No, they just got it in so even the staff didnt know much about it. Probably take some time before its properly launched, I will try and review it and compare it against the S17 Pro Evo. I did try SR7000 on both, and the slam and dynamics seemed better on the A17 than S17 Pro Evo and with even more headroom. But it was a noisy show floor and hard to really evaluate it, I focused at trying the AR9000 instead when the doors opened on Sunday and was less noise so I could help them on which variant was the best of AR9000. The variant one had more fun bass response and was fun but the version two seemed more high end to me and balanced, I trust Aune to have heard feedback from many of us who heard it and will improve if needed.
Price is not decided yet, but will be some. Its a beast of a amp.
