+1 for Bluesound. It competes really well against my much more expensive analogue front end and although I have not done any side-by-side comparisons, like @deadhead1000 said, I’m guessing I’d have to spend a LOT more (even used) to get substantially better.
I run mine wired but I honestly can't tell the difference between wireless and wired. Paul from PS Audio has a YouTube video on this...and he makes a good point. I ran my Amazon TV box over Wi-Fi for years into an OLED TV and just hardwired it - no difference at all. BUT, it makes sense to hardwire especially if you have a bunch of devices in the household using Wi-Fi as most of us do.
