Warming up digital in my setup

You got what you paid for.  Need a separate DAC.

Hey martinman, you and I seem to have similar priced setups at the moment. I believe I may have some insight for you. My system is as follows:

B&W CM9 S2
Peachtree Nova 300
Jamo sub
iFi Zen Stream + Roon (Qobuz & Tidal) with USB out

I've experimented with networking and power stuff--and I'm going to experiment with DAC's next--but for me, the big level up was moving to the iFi streamer. I wrote a little review with some thoughts, which you can read here on Agon. Some of the only other things that could compete with the level of improvement were adding a sub, adding nicer feet to the speakers/stands, and placing the speakers on stands. 

+1 for Yggdrasil!

Seems you’ve accepted that your DAC should be replaced.  If so, stating your budget would help us narrow down DAC options

I wonder how much of an improvement you can get with a dedicated streamer vs connecting your iPhone via USB.  Is there any way you can borrow something like a Node or a Zen Stream just to test?  Or maybe buy a Wiim Mini for $100 and use the digital out into the DAC in your Hint6 to see if the iPhone is your weak link.
