There isn't any manipulation with lossless compression. After a file has been compressed and then expanded the result will be a file that is an exact copy of the original file. (Neglecting any issues with headers that may have been changed by other software that is not part of the compression process.) What this comes down to is that the net result of a lossless compression followed by an expansion will be no different than a straight file copy.
Whether an original file and a bit for bit copy of the file sound the same is a separate question, having to do with the computer system hardware and the operating system and player software. It has nothing to do with the compression/expansion processes, since these processes will not be in use when the two copies are played.
