That would be nice if they could pull it off, but I take a contrary view. Chord has shown how difficult it is to do software with the Poly (and 2Go), and they are clearly still very very far from the standard that Rob has set on the FPGA and HQ sides.
When there is a successor to DAVE, I hope it reflects every atom of Rob's considerable talents in designing the ultimate DAC, and is not held back for what could be years for work on the software and network side. Connecting a $500 NUC running Euphony to anything that Rob designs will be light years better than anything Chord is able to do on an integrated unit.
As an aside, I suspect the path for summit fi DAC's will be more separates (DAC unit, upsampler unit (mScaler), power supply, reference clock, streamer end point), each pushed to the very limit of quality. We're already more than half way there with DAVE and mScaler and a premium streamer box like the Innous, and folks are DIY pushing it farther still. Of these pieces, the streamer is the piece that is cheapest/most off the shelf, and the one where technologies change the fastest (every 12 months or so). I don't think most folks would be happy dropping $50k on a flagship, and having the streamer component already out of date a year on the day they purchase it.
All that being said, it is very very easy with today's DAVE to be pushing a $30-40k digital chain, so the market is certainly there for that level of summit fi at the flagship level. I'm sure has their eye on that market. Can't wait to see what sonic miracles Rob is able to conjure with a "BOM be damned!" design remit!
