Anyone using an Audiophilleo with Audio Aero?

I have an old Audio Aero Capitole Reference with digital inputs. To play music from my computer I bought the Aerobridge from Audio Aero. This is basically a HiFace1 and it works well.
The digital music does not sound as good as the same CD played.
I can either use a Windows machine or a Mac mini so computer or sofware is not an issue
I want to upgrade to something like the Audiophilleo (or something else) and am looking for advice and opinions.
So,Audio Aero owners that are using usb/spdif converters please let me know what you think.
