New Cary DMS 700

I'm just now looking @ the 600 - though in my quest and more so confusion.   What's the best way to connect a music server/streamer?

USB as in the McIntosh C53?

I have a 1tb ssd connected with USB. Also a 128 G SD card into its integrated SD player. You can use its digital usb out if you want to use it just as a streamer or any of its digital ins to use as a Dac.  Very flexible peice.

I owned a couple of Cary pieces in past. First one was a new tube amp that had design flawed and was charged over 1k to upgrade to “MKII” to correct their mistake. Next I bought their flagship preamp used which turned out to be manufactured out of phase. IT WAS BUILT THIS WAY INCORRECTLY!  After multiple calls I had to send back to them at my expense (and return shipping as well) and they finally admitted it was built wrong but I had to pay to repair to get to the way it should have been built.  Poor quality control, useless customer support. Only plus is they are built in USA but they behave as if they were from China. I will NEVER purchase any Cary product again.

Looking hard at DMS 700, but not sure if I want all in one or separate pieces.  Alternative combination is Aqua La Voce S3 w Evo 432 standard streamer.  Anyone care to chime in on what would be the better sounding set-up?
