Volume loss converting DSF to Wav with Convolution

RE: Volume loss converting DSF to Wav with Convolution
The ffmpeg command is generated internally by MinimStreamer. For 24/176 output, it is:

ffmpeg -v 0 -analyzeduration 0 -f dsf -request_sample_fmt flt -i filename.dsf -vn -ar 176400 -f s24le -acodec pcm_s24le -sample_fmt s32 pipe:

or with soxr enabled:

ffmpeg -v 0 -analyzeduration 0 -f dsf -request_sample_fmt flt -i filename.dsf -af aresample=resampler=soxr -vn -ar 176400 -f s24le -acodec pcm_s24le -sample_fmt s32 pipe:

I have tried a few combinations just now. In my system, increasing the output resolution to 32/352 improves the sound. Enabling soxr also improves the sound but not by as much as changing from 24/176 to 32/352.

Any suggestions for changing the ffmpeg command to get better results would be much appreciated.
