Unfortunately I cannot personally speak to the Reference line but I will say that the Reference XL is first rate and provided a good step up in performance when I upgraded the three clocks in my DCS stack from the AQ Eagle Eye I was using before. I'm currently contemplating a further upgrade to the Ref XL AES/EBU replacing the AQ Wild I am currently using.
If the big brother is anything to go by you should be very pleased by the Reference line
