Yashu:

Your concern about resampling is a good one - Audigy 2 cards were really famous for resampling everything to 48khz even if the "final sample rate" was 24/96. The Audigy 4 uses the same engine (I am told) as the Audigy 2. They just added ASIO support and used better DACs.

I think if you're using the NATIVE ASIO drivers with Foobar and the ASIO output plugin you should be okay. You do need to set your bitdepth to 32 bit when using the Otachan ASIO output plugins for Foobar. I do not believe this converts all bitdepths to 32 bit - it just opens a 32 bit "window" (like a container size) and whatever is played back uses 16, 24 or 32 of those bits.

If you are indeed getting audio out of the digital out using a NATIVE ASIO driver, then you might well be getting bitperfect playback.

Google the DTS file bitperfect test. If you can play back a 44.1 khz DTS file and an external decoder recognizes the signal AS a DTS file, then you KNOW you have never resampled that data.

If you don't have a receiver that displays the input stream data (bitdepth and samplerate) perhaps you could borrow one. It should say "44.1khz" and not "96khz". If you can manually select 44.1 khz, this is really a good sign.

Hope this helps.

Cheers,
Presto
