Can't really answer that. I don't get hung up on DAC's too much - guess I am old school because the power & build quality of an amp that translates into its sound qualities is what comes first in my book. I have a 2 channel system embedded in my Home Theater system thanks to an HT bypass feature on my 2 channel pre-amp. I rely on my AVR that acts as my processor for any DAC needs. I believe it has Wolfson WM8740's - pretty decent ones from what I can gather. The NAD has a highly regarded Burr Brown PCM1796. Very good also.
Since I consider good robust amplification to come first, I still like the NAD. It produces 80 wpc and weighs 19 lbs plus. The Rega produces 50 wpc at about 13.5 lbs. Also, the NAD is more of a conventional design both in size and control while the Rega is more minimalist in appearance and control. Again, these are my preferences and not meant to knock the Rega but its small width would bug me aesthetically. I just think the NAD is a more powerful amp and this should be the first thing when considering an amplifier - does it produce more power than you need right now and just as important - will it produce enough power for your future needs when you upgrade. The NAD stands ready to grow with your system.
Hope you get other opinions so you can make the best decision possible.
