I replaced my EtherRegen (fiber into the A side) and LPS1.2 power supply with the following converter and an iFi power supply. I couldn't hear a difference after the switch. I purposely picked the StarTech just because it wasn't the cheapest (actually is pretty pricey compared to $20ish ones on Amazon). I have no idea if it makes a difference over the $20 ones but bang for buck compared to the EtherRegen was a big bonus for me at least. Just adding 10 feet of fiber between my router and EtherRegen or StarTech was the biggest improvement for me, outside of buying a pretty decent streamer.
