Phil,
Have you tested the Portta for anything higher than 24/96 yet? The advantage of the Atlona (so far, before Phil tests) is that it works all the way up to 24/192. Read my thread....I grabbed 24/88.2PCM from Oppo's SACD (DSD converetd to PCM) and grabbed 24/192 BluRay audio too.
The BDA-1 is a DAC you guys have already invested in; Phil and my point is: use it. These very inexpensive HDMi de-embedders allow you to leverage your investment in the BDA-1 and use it to capture BluRay and SACD 2 channel digital stream from HDMI (there is no other way to capture them digitally, short of modding your player with expensive SPDIF boards).
