The real issues are going to be related to device compatibility with modern iPhone or Android devices, as well as streaming services. So long as that's up to date you should be good.
Ayre QX-5 Twenty
I have been looking at a few DAC's and Ayre QX-5 twnety is one of them. It checks a lot of boxers. It has a built in streamer, headphone jack, and a filter for video which I like. I just want to make sure the technology is still up to date since it has been out for so long. I know that Ayre has updated the network card and usb port. I found out the unit has an FPGA chip that is updated with software when needed. It has the last generation ESS chip not the one just released but they don't use the filters on the chip. They said they only use about 5% of the chip's processing power is used. Let me know if their is anything just as good for the same price.
