The NAD T751 was the one unit I considered before ordering the Outlaw 1050. I have had a NAD T770 for a couple of years and it is a fine product but I wanted something less expensive for the second system I'm building. There are some very bad stories on the net about the NAD T751's reliability.
See, for example:
