I have a Soekris DAC / Bruno Butzey's Balanced Pre project that I've also listened with the Purifi. That Balanced Pre uses the same LM4562 opamp in all stages including the output buffer. Power to the BPBP module is provided by SilentSwitcher. Both me and my friend found that sounding inferior to the WHAMMY buffer doing the same function. Interestingly it was not only low end control but also the depth of the sound stage and sort of 'air' that was missing in BPBP. At the time of listening the power supply for both cases was the SilentSwitcher module.
The Neurochrome is a different circuit of course with only the opamp being the same (and there is only 1 in signal path instead of 3 in BPBP). So it is sure possible that it achieves a different result. It would be kind of interesting to get two modules and try them out in apples to apples comparison, but for me being in EU it'll probably cost quite a bit more due to +20% VAT on modules + shipping.

I am making some progress on finalizing the WHAMMY based solution too. I had bought some Jung/Didden Super Regulator PCB-s times ago for ... I don't even remember what for. Anyhow, this project was a motivation enough to finish those. So the plan is now to have a MEAN WELL IRM-20-24 AC/DC unit supplying each positive and negative power rail for the buffers and each channels gets their own. So basically a dual mono build from buffer power supply perspective. Waiting on MeanWells to com in to put it all in action.
