Sorry Cujo, but the best analogy I can come with is.......

You have a fantastic 3-course meal available to you at ANY time of the day or night.....flick a switch and it's there in front of you

But instead you choose to get a burger delivered from the local fast-food joint......fine for a quick fix.......but not a substitute for the always available 3-course meal above

And you've no doubt guessed that the Airport Express and Airplay are the "burger" in this analogy!!

The AE will alter and compromise the sound and NO amount of playing around with it.......or adding special equipment or "sauces" will ever allow you to recover the damage already done by the AE

The "3-course" meal here is to simply use your MS200 [or upgrade to an MS600......or even better the 818v3]......and use that to feed your DSP's.......that is the best solution and the one you should use 24/7/365 IMHO

You might also want to try Roon.....which allows a variety of devices for UI........and will also play the files to your MS200

FWIW, the AE will resample EVERYTHING back down to 16bit / 44khz........so even 24/96 files are resampled to 16/44......resulting in compromised sound.......and this doesn't even mention the huge amount of jitter typically added by the AE
