ASIO Driver mode: PCM / DSD (Autodetect) difference
DSD2PCM mode: Multistage (fixed point) / Multistage (floating point) / Direct (Floating point, 30kHz LF)
What's the native sampling frequency for SACD?

As quality goes, the DSD (resulted from SACD) is equivalent with PCM 24 bit 96kHz... So the 176.4kHz might be overkill, but some might say 88.2kHz is not "complete". As in it "goes" only to 40kHz instead of 50kHz
2822.4/24=117.6... 117.6KHz isn't a rate so we have to do 2822.4/32=88.2. I don't think the plug-in outputs 32-bit, so it would have to be converted to 24-bit. This would keep about 75% (24/32) of the DSD's audio data.
I think mine foobar shows an astronomic samplerate when I open SACD ISO, so it must be divided by something. I don't even think music album could fit on SACD with so a high samplerate.
Actually the definition of DSD is 1-bit with 64 times the CD samplerate
So if you want precise calculation, you have 28822.4/16=176.4kHz@16 bit.
I tested it (ver. 0.5.3), and it outputs samples in 32-bit float format (as it should btw). So it doesn't perform dithering itself.
