It's probably the UcD line that has "some" NCore technology.
Had the opportunity to have a chat with Bruno at the Munich High End last week. NAD in their marketing material says the output stage is "licenced" from Hypex, but Bruno said it's a Hypex UCD module
I have a D3020 and am absolutely delighted with the performance for the money.
It's being fed by Qobuz > Sonos > miniDSP with Dirac > D3020 > KEF LS50
Most of the conversation was about the Mola Mola DAC as described on the Mola Mola blog. I tried to persuade Bruno to do a DSD only version,with lower parts count and cost for the DIY market. I said to Bruno that PCM to DSD conversion software had gotten so good that the case for a DSD only DAC was pretty strong
