。The Aurora16's biggest competitor is the Apogee AD and DA 16X units. However, you are looking at double the price of the Aurora for that solution and there's nowhere near as good integration with PT|HD if you ever plan on going that route. Really, you can't go wrong with the Aurora. It sounds incredible, is really stable and has a host of i/o options including PT|HD, FW, ADAT and of course the included AES/EBU. Iit's sound wider ,three dimensional, low-end clear,transparency.
