I have an Aurender A1000 on order to play with. I ordered it ostensibly to get audio out the TV. I used TOSLink to the MSB for audio from a Sony TV without issues. New Samsung (x2) produces 1-2 second gaps three times when a new stream starts. Oh, but the nice OLED 65 inch screen is magical.
And, I will be experimenting with USB out to the MSB premier, and trying the digital streaming using Conductor, and even as a Roon endpoint (compared to the MSB Renderer)
Lastly, I try to have some sort of “project” to work on with my son (visiting from Sweden) This year we will be tackling a custom keyboard build.
