Yingtonggao: Hi, I have never had the privilege of auditioning an Off-ramp 4 or any Empirical Audio gear for that matter. I did compare my (former) Sonicweld Diverter HR and Kingrex UC192 to the USB port in the AMR DP 777. To be succinct it was the only time I preferred another interface to the Diverter HR. It is very good and though the XMOS chip is used it is not that simple. AMR wrote their own USB code, it is not licensed from wavelenth as so many others have done.
Also the I2S is a definate plus as it is one less conversion to be done.
The Diverter HR was close when feeding the HD-VDi input of the AMR but at the end of the day I thought USB direct in the AMR was best... that's why I sold my Diverter HR.
