Recommendations on a Warm Sounding DAC under $1100.00

So it seems you want to try a tube DAC that has both USB and I²S inputs and costs $1,100 or less. The Cayin iDAC‑8 Dual Timbre is the only option I could find for you. However, I’m not sure whether the Matrix TT‑1’s internal clock circuitry might have a similar incompatibility issue with it.

Thank you so far for the responses..

@lanx0003 I’m not locked into a tube DAC as an option, really looking for something just not so forward.I’d really like something that is warm sounding if at all possible. For laughs I tried a FIIO BR15 R2R just to hear what an R2R is like without breaking the bank. It’s ok, returned it though being I would get static on anything streamed on 48kHz. 
Thinking about the new Musician Pegasus III or Laiv uDac as possible options.  

Try the Holo Audio Cyan II R2R DAC. I've enjoyed mine for 2 years, and never found it to be a weak point in my system.  Sounds fantastic using the I2S input. 

used pontus

mhdt dac

used van alstine tubed dac

used metrum

all the above should outperform the glass ice/jolida fx, based on my experience

Holo springs don’t know the model very good feedback and reviews.
