Tube DAC with i2s input?

OP:  I’m looking for better depth/dimension, separation and analog warmth.

I have a tube DAC (MSRP: $12K) and a SS DAC (MSRP: $6K).   Both offer depth - dimension - separation.   Both sound quite good - just different flavors.  Neither are harsh or fatiguing.  They’re very musical.  Yet years ago, both did sound harsh & fatiguing.

My interpretation of analog warmth is the absence of digital distortion.   That is accomplished through cleaning up the signal and the power in the digital chain. The effort is worth it.  Good luck!

Neither has I2S

I would think the price range you are listening, sound quality would be greatly more important than connection type. So between similar priced DACs the sound quality  might vary by say from one to ten and the variation in sound quality  because of it’s connection type might be .5. 

@steakster Thanks for replying, what is your $6k DAC and what did you do to clean up the power and signal? I do have a Niagara power conditioner and as far as signal I primarily listen to CDs on my digital side. 

@ghdprentice I'm concerned with i2s so I can still use a DDC into the DAC. 

Look at a Terminator 15th from Audioman58. About $5500 from him. It will accept your i2s. It R2R and excellent.

@fthompson251 Thanks, Terminator is top of mind for me, I wish there were more comparisons between it and tube DACs so I had a better info. My amp is tube based (Rogue Audio), and owning a Pontus and liking it (but not loving, as mentioned I wish the quality of it was richer with more air and especially depth). I imagine the Terminator would provide much of that but would it be as good as an equivalent tube DAC?
