I wouldn't be sure on that power rating from Teac. It appears to weigh the same, or at least very near too, what mine weighs. Now they might have adopted the Class T amplifier into their micro products, and it may sound great. I have no personal experiance with Class T amplifiers.
What speakers will you be using? My Boston HD10s get plently loud for me (and I am 21 and love loud music) being powered by 25 watts per channel of Class A/B power. It runs very cool and has stunning build quality and SQ. The noise floor is very low on it for one thing.
Which NAD do you refer too?
Let me make a few other suggestions, sense we are discussing Teac.
The AG-H550, a 5.1 surround sound receiver, is a half size component with all the heft of a full size receiver. It looks like a wonderful piece of equipment and has plenty of power. You can find it on Amazon along with the matching DVD player. They come in Champaign finish, they look very elegant.
