Hello,

perhaps somebody can explain meaning of SACD decoder options.

ASIO Driver mode: PCM / DSD (Autodetect) difference
and
DSD2PCM mode: Multistage (fixed point) / Multistage (floating point) / Direct (Floating point, 30kHz LF) difference

I'm utterly aimed to get highest quality for converter..

What's the native sampling frequency for SACD? I have 4 choices which 44.1 is too low, but there are higher. I intuiitionally choosed 88.2kHz but not sure if this still isnot downsampling the undecoded audio. I need a value that won't up/downsample the audio any way and extracts in the same reate as original. Thankyou.

I'm almost 100% sure that your soundcard doesn't support DSD input stream, so there's no difference.

floating point is faster (at least here, on Intel Core2)

And what's the impact on audio quality between the 3 modes, or is the output always same regardless the mode?
