Re: Wav volume changing FLAC sizes

If you want to peak-normalize, then why not use the ReplayGain peak rather than the +6?
The SACD 1-bit signal is not a 16-bit PCM, so it cannot fit into a 16-bit .wav. Anything below is cut off, if you do not dither:
You will fill the 16 bits with "bits 1 to 16", and bit 1 is always zero and easily compressed away.
If you bump up the volume by 1 bit (approx 6 dB), then what was bit 1 is "clipped away" (which makes no difference since it was always zero) and what is fit into the .wav file is "bits 2 to 17".
So you take out the all-zero easily-compressible bit 1 and throw in the mostly-noise hardly-compressible-at-all bit 17. No wonder it gets larger.
