Just to add to what Gianluca said about OSX. I’m sure Jussi said somewhere either here or over on Computer Audiophile, that NAA only does core audio on MAC’s even those with Exasound DACs and ASIO drivers. I know this as I have one and cant get the NAA to use Exasound’s ASIO drivers. The drivers only work when HQP is on the MAC itself and an NAA is not used.
