Recommend a DAC

[TheOldPresbyope]

Depends on your budget, if you've got £14499 (or $17250) I've heard the DCS Bartok is pretty good.

WOW!  I just want to better sound to my google max speaker?  Not more then $70?

So something like the low-end US$10 Adafruit dac or the US$35 HiFiBerry DAC+. 

If you ever move up from that Google Max speaker you might want to consider a modest USB dac in the US$100 to US$250 range. There's lots. See for example the audiosciencereview listings.
