I have a Maplin power supply for my rDAC and you can set the polarity. I've checked it's correct for my rDAC but what if I got it the wrong way around? Would it damage it ?
Synology DS212J-> AppleTV-> rDAC->Naim Nait5i. Dynaudio Audience 52SE
Sony BDPS370 / YouView ->Yamaha RXV1065-> Pana TH42PX80B plasma.
If the rDAC doesn't have diode protection, yes you will damage it.
Best check with a multi-meter if you are not sure.
