Guys, he has the MacBook already, and he hasn't yet explored the free and low cost options. If he configures the Mac properly and tries adding a $100-150 USB-SPIDF converter, and he still doesn't get the sound he likes, then by all means replacing the Mac with an Aurender or similar dedicated streamer makes sense. But until then, it seems irresponsible to recommend replacing existing hardware for thousands of $$$ when there are free and low cost options that can make a world of difference. In particular, the USB-SPIDF converters can do wonders for cleaning up noisy USB signal. I don't doubt that some of you can here the difference using a purpose built streamer, but that doesn't mean it should be the recommended solution of first resort in a situation where OP already has hardware.
My two cents, of course ...
