Is that the SPA22? From looking at the specs it appears it does not decode dts HD MA, TrueHD or accept discrete analog inputs except for stereo. How are you playing Aqualung Blu-ray with it?
Yep, it is the SPA22. I bought mine with an included HD Audio sound card, so it decodes all HiRez formats. In addition it do accept discrete analog inputs for 5.1 as a standard. Highly recommended!
