I've heard this combo and would not recommend it - the new hybrid digital NAD amps don't seem to play well with the LS50. The now discontinued 50 Watt class AB integrated they made(can't remember the model) was a much better match even though it was lower powered.
The Yamaha AS801 worked a lot better as it has a bit warmer sound signature and the two seemed to mate very well together - a combo I could easily live happily ever after with.
If you can try before you buy go for it you may well love it, the amp definitely has enough drive but they sounded harsh together to my ears.
Good luck!
