Everyone has their opinions and their ears, but mine tell me that the Aurora-16 is wonderful!!! I love mine, and can't imagine living without it! I have had mine for over a year, and have never looked back or regretted the purchase for one second.
Mine is internally clocked, and hooked up to a Lynx AES-16 interface.
Best of luck!
