If you have the opportunity to hear it for yourself that would be preferable. If given a choice I prefer the NAD for a number of reasons including the effortless power and very musical sound. Rotel is often more detailed in the upper midrange but the NAD just gets music right.
The Rotel is a little mechanical sounding,and can get fatiging to listen to.
New 352 owner here and very pleased. Paired with Monitor Audio S6 and NAD 542 CDP. For the money, it is a solid piece of equipment. I did not compare it to Rotel, but did compare to Arcam. Arcam was excellent and had a phono stage, but was a lot more money and I was not certain I could hear that big a difference.
