Yeah, I've never had any interest in Wavelength's DACs. Too much toobophilia and associated deviant beliefs.
But as soon as I heard he'd licensed WaveLink (his code stack for the TAS1020B) to Ayre, it was pant-wetting time. Gordon used to be a programmer and that side of things he has locked down. In operation, it's been completely bulletproof and really seems to do what it says on the box.
Dan, it'll be interesting to see what j4cbo comes up with. From what I understand, it's a shedload of work implementing anything along these lines.
