I used to own the AS Mambo. An excellent turntable. Very very good design. I haven't heard the Nott's but also a good design from a motor standpoint. In my experience, low torque AC motors is the way to go. The important advantage I see the AS having over the Nott is the very heavy platter. This in conjunction with a low torque motor will give great speed stability. Plus a solid/heavy plinth will make the bass dig deeper.
If you can get a Mambo, you'll be happy for life. I wish I had never sold mine.
