I think the sound of a Mini with an upgraded power supply outputting to a Dac is great. I use an Sbooster with mine. Retail on the Mini was $550 without the upgraded LPS my Sbooster was about $350 making the retail $900ish. Not sure what Auralic charges for their LPS. I see a Mini on here now with LPS for $620 that's a tad high reflecting the scarcity.
As far as dropouts I had no issues at all with the Mini on wifi and now I have it hardwired. Every once in a while issues pop up but they are typically an issue with Tidal or Qobuz rather than my Mini. I hope that helps.
