Yes. The decoded output is bitexact to the original source. You could do ABX 
tests to convince yourself though :-)
And please do not pay heed to the doubting hordes at Hydrogenaudio who say 
that the encoded audio "lacks bass" and assorted nonsense :-) [1].

I'm no expert but I think you don't need any listening tests to confirm if its 
lossless.
