Nad 748 receiver as a prepro ?

my prepro bit the dust, I was thinking of getting a nad 175 hd prepro, but I saw where nad just came out with a 748 receiver which has hdmi 1.4 and arc, would I be loosing anything by using this receiver instead of a prepro, thanks
The 175 hd will be a much better sounding unit than the 748 (which replaces the 747). I had the 747 and upgraded to the 765hd2 receiver. Quite a substantial gain in performance. Assuming you have a good power amp already.
