Hi Audiozen, I'll try to find out what NCore module there is inside REF500. As for power supply, I have heard that each mono chassis sports its own Hypex NC1200/700 SMPS, which is powerful enough to support even the full blown 400W 38A peak current of NCore NC1200. This means that the 300W/8 600W/4 at 27A peak current can be supported with plenty fheadroom to spare.
On REF600, John Stronczer seems to have concentrated his design work on the custom differentially balanced input stage instead.
One useful feature of REF600 is the internal DIP switch to change gain from 27dB to 33dB.... This will be quite useful for use with lower efficiency speakers, such as the Maggie 3.7, and probably my own Vienna Die Muzik which has a bit of a wilding impedance curve.
