As title, I ABSOLUTELY LOVE my x7 - however its unreliable and ANNOYING AF. It won't seemingly take any firmware updates anymore so I can't get any bug fixes and it often just cuts out and needs to be turned off/on again many times before it decides it wants to connect to my Mac mini OR PC. I have a USB switch with the X7 and mouse plugged in so when I want to switch between machines I just hit it to move between - it is not this though, it behaves the same if its directly wired in to either machine. So because of this iv had enough, it sounds incredible but it just can't handle being reliable - I need a sound system that just works no matter what. Its hooked into a pair of KEF Q100 speakers so I will need a new USB soundcard/DAC to be able to handle that & handle speaker wire (not 3.5mm). Must work with both Mac & PC Suggestions ?
