I have only read great praise about the sonic performance of the Aeris, however there are a couple of technical issues that prevented me from considering it for my system. First is that the USB input is limited to a 96kHz sampling frequency, and second that it does not support DSD decoding. These issues may not be a concern for many users but were a deal breaker for me and I thought you should be aware of them. The SPDIF inputs support sampling rates up to 192kHz.
