Looking for a good DAC under $500

I agree that at the $500 stated budget the internal BSN2 DAC is likely to be as good. Now, use of an older used DAC having a more robust power supply and better analog output stage, such as the aforementioned Bryston BDA-1 which could be had for $750, would likely make for an improvement. 

I looked but had trouble finding a LPS for the Cambridge DacMagic Plus. Does anyone know where to obtain one and what the $$ is?

Can you describe what a good LPS does for the sound?

Thanks!

This might ruffle a few feathers but do yourself a favor and take a look at HiFimeDIY. Some of their offerings use same DAC as Oppo players. <$100. Yes, their stuff is likely made in in China but somosnthe iPhone and just about everything else. https://hifimediy.com/

For the guy whining about members not doing their research.... 2 comments, when you are looking for the next piece, 1) with so many smart and experienced “audiogoners” out there why re-invent the wheel?  2) With so many offerings out there WHY NOT supplement your research by asking a large pool of audiophiles what they are using?

I really like the Chord Mojo which can be had for $500 or thereabouts.
