Bluesound is probably the best bang for the buck. They have excellent customer service, too.
I think the only other product that might be considered is The Memory Palace, but even the Mini is over $2K, so you pays your money, you gets your whacks.
I took a quick Google, and it seems there is a bug with the BS Controller.
Unfortunately, the site seems to be down, so I couldn't find out more. In any case, why not contact Bluesound? Maybe there is a fix.
