Oppo Sonica DAC for streaming Tidal

Totally agree. Mine has about 150 hours on it 

Hello joining late to the convo and I have a different type of question. Currently I stream my itunes lib over my network to the DAC over the ethernet line.  I was considering hooking my external hard drive directly into the DAC via USB.  My question is would I hear an improvement in overall sound? Opinions please!  I love this DAC I had a Sim Audio 100D, this for my system and ears opened things up and bit and the music sounds more controlled with imaging and depth.

I have the Sonica Dac (modded by Audiocom UK), I love it the sound is amazingly good and the unit has some great features. Although it is quite hard to fault there some caveats to consider as it is not quite futureproof

• No support for gapless playback
  
• No Digital XLR input
• Not Roon Ready or likely to ever be (I have contacted OPPO directly a few times)
• No firmware update since May 2016 ( only an update for iOS 11)

In 2018. I plan to upgrade to the PS Audio DSD DAC as this will provide all of the functionality and quality of sound to compliment my set up.
