Has anyone used the USB Input on the Musical Fidelity A 1? Putting together my first system, and have owned this amp now for a couple of months powering a pair of Klipsch Heresy ii. I am using an older Sony cd player, but thinking about purchasing a Mini Mac and using it as a server into the USB/dac on the A 1. I am curious what file types it will accept? And if the built in dac will be much of an upgrade over my old Sony. Looking to start ripping my cd collection so knowing the correct file type to rip to will be a big help. Any advice would be appreciated.
