IIRC, the SNR/Dynamic ranges are much lower then the current heavyweights. The 300 is listing about 120dB (spec) so about 117dB realworld.
So, technically it is not even up to the same specs as CL or ASUS current offerings and as far as specs go about the same as the Prelude, Forte..etc
Now, with the improvments in the circuitry that onkyo is suggesting you may have excellent noise and distortion charactheristics but that reamins to be seen or rather heard.
I am not trying to form an opinion before I hear or measure the card just stating fact of the released information.
