I was running that on wifi via iPhone hot spot on my SC5000M. But I had also connected x1800 and 3 more decks on LAN 2x normal SC5000 and one more M. In this deck were all 3 USB ports occupied and still soundcloud worked ok. No issues. Also reverted back to play from usb without a glitch. Switching off and on - as usual. All 4 decks behave like they should.
