I wouldn’t buy anything based on Android 11 OS. It was End of Life Jan of 24 with no further patches and security updates.
They are approaching the price of Innuos and now Aurender. Buy one of those and get great hardware and even better support. You are buying into a platform / ecosystem.
Aurender and Innuos can remotely diagnose and correct many problems.
A6 McIntosh DAC users can no longer connect via USB since last update. They are having USB problems with other brands USB. Unresolved since June and Jan.
Their suggestion? Roll back firmware. Visit some foreign site with no affiliation and download FW. They would not directly send it saying it was dangerous to roll back firmware??? I’m dead serious. That’s the level of support you get. So I waited 3 FW revisions and still no USB.
Their support is to visit their user forum or exchange through dealer. Exchange for another unit that’s software is bad? Makes no sense. $1299 , $2000, and now $3700 ? As a Bluesound and Aurender owner and tech support for my Dad’s A6 I suggest spending your $2k to $4k on a company that won’t let you down after the sale. That’s a lot of money, spend wisely
