Run Roon in an iMac or dedicated Mini

Don’t know if this helps but I have an M1 Mac Mini as my core. Then an internet connection from my router to a Bryston Pi as a Roon endpoint. From the Bryston I use a USB cable into my Ayre QB 9 Twenty DAC. I use my iPad as a remote. The only problem I’ve ever had was when the Roon application crashed on my Mini. 

dpphd, I originally bought my QB9 when it was in its first form. I believe around early 2011. I compared it to a tube Wavelength DAC at the dealer and the QB9 crushed it. Later Ayre offered a $500.00 upgrade which I opted for and the improvement was very noticeable. But I was not ready for the Twenty upgrade! It is a different DAC altogether. I'm running the DAC to a beast of an amp, an ASR Emitter II Exclusive with HiDiamond interconnects and then to Quad 2905 ESL's with HiDiamond speaker cables. The soundstage is holographic. Fast transients. Deep articulate bass, rich and detailed midrange and the higher frequencies roll off just as one would hope with analogue. I love playing DSD and high definition files. I think you'll be amazed t how good the Twenty sounds regardless of price point. I would add, that my local library fairs better than Tidal or Qobuz but I'm not really set up that well for streaming yet.

dbphd, I use the ISO Regen with LPS 1 but with the QB9 Twenty, it's probably not necessary. I'd like to hear what a difference the Ether Regen would make in streaming however I've got other priorities.
