OK, which one?

The DAC in the WiiM Ultra is good enough that I sold off all my stand-alone DACs, all of which cost significantly more than the Ultra.
 

Get both and return the one you like less

@audphile1 + 1 - I think they're both available on Amazon so should be easy to do.

@audphile1 , genius! I swear I’m getting denser all the time. Easy enough solution.

But, I’d still appreciate your learned opinions.

@goodlistening64 ,

Bash my legacy dac again and I’ll clock you with my triangle!😆

I have the Wiim Ultra and using the DAC in my Yamaha rn-2000a.  The SMSL PO100 Pro made a significant difference in the sound in my opinion.
