RE: Those who have compared both

I suspect improvements will be very small and no reason to change from a 1st to a 2nd generation Purifi amp, but if moving from another Class D (or any other technology), it is probably best to look for a Purifi amp with a 2nd generation board.

Much bigger differences are likely according to the implementation of Purifi. There are lots of "garage-built" Purifi amps that use the cheap Eval(uation) board, whereas others such as NAD and T+A build under license after authorised tweaks to maximise performance and the use of superior additional components such as power supply. Just look inside these amps to see the difference in power supply, RFI-protection measures, etc. Not all Purifi amps sound the same!
