The seller stated that he just swapped the DAC chips - I guess it's a bit of a lottery with these chips. I've had a TeraDAC HAT based on the 8xTDA1387 for over a year now and it's been fine (though not as good as the Proto). I'm still on the fence about buying a replacement because of this - if only I was handy with a soldering iron!!
