I've recently upgraded my DSP8k's to SE and bought the 818v3 to replace my 861v4. The sound is fantastic. I expected to only use it for Tidal but after listening to some high resolution music on an MC200 I'm hooked! But now I have a few questions.

1. The QNAP solution looks a lot cheaper for more storage. I can get 4 TB for a third of the price of the MC200. Is sound quality comparable? Don't quite understand the advantages of the MC200 and why it exists.

2. I would connect the Internet router to a switch and then connect the 818v3 and the MC200/QNAP to the switch using RJE cables. Has anyone noticed any differences in sound quality depending on switch quality or cables?

I have been recommended the audio quest diamond RJE which are about $25 an inch in order to minimise noise. But I can't help thinking that most Tidal noise will come from my internet connection, and then having these from the high res source to the switch and switch to 818v3 most noise will come from the switch.
