I'm going to take my standard approach on this one and ask:

Why do you want to convert DSD to FLAC?  MC can convert DSD, on the fly, to whatever format your DAC supports.  If you intend to replace the DSD files with FLAC copies, those copies are going to be pretty darned big.

If you want them for portable use, maybe it's valid, but do you really want high sample rate FLACs?  Or would high bitrate MP3s be just as good for portable use?

In Convert, click on Options, check Apply DSP and select DSP Options. In Output Format, set 352, 704, and > 768 to the final format you want - like 176.4 KHz. I am away from home and only have MC 20 on this computer, but I think the 704 and 768 options are in MC 21. I have 384 KHz as my maximum.

When you convert DSD to flac you need to filter out high frequency noise. By default, MC uses a low pass filter at 24 KHz and 48dB/octave. I think that is too aggressive and think something like 50 KHz at 48dB/octave is more appropriate. I believe the 50 KHz filter is the SACD standard. The default filter is set in Tools- Options - Audio - Advanced - Input Plugins - DSD. I disable the filter there and add the 50 KHz at 48dB/octave filter in the DSP options in Convert - in Parametric Equalizer.
