A warm DAC?

neko d-100-2 is very nice too... output transformer coupled, warm nature very easy to listen to, picked one up recently, quite impressed

as for units mentioned above:

rme adi2 is a really great dac but it is NOT warm... it is very good akm implementation - clean crisp tight focus revealing... not lean and strident but not warm

same for chord dacs - i have qutest, 2qute, mojo, soon to be adding an m scaler to qutest -- they are also not warm.  the sound has body and foundation but there is startling clarity and detail... not warm side of neutral imo

I'm amazed at the amount of different DAC's are out there for under $1500 that can be bought either new or used.  Makes the buying decision more difficult though.  Almost all mentioned get good reviews.  
I think my route would be to first look at one's that offer a free trial period or if I can get a good deal used, buy it and if it ain't for me I'll resell it.

It's possible to change the tonality of any component by changing the IEC inlet and power cord plugs. The effects of these components can be more pronounced than rolling tubes. I have experimented with amps, DACs, a power conditioner, and power cords. Just as you would expect: the more gold, the more warmth and ease of listening and the more rhodium/silver, the more detail and neutrality. 

I can offer a recommendation based on my personal experience. I too like digital that is reproduced with the analog “warmth”  “lush-ness” “musical” pr however else or ears tell us to describe it. I found it with The Aesthetix DAC  in my Romulus model. The DAC only is the Pandora. Maybe preowned would fit your budget. As a starting point, you could then roll tubes to suit your taste. I went to telefunken and amperex and am very happy. Also With this gear, you could have the caps resistors etc upgraded by Aesthetix to really impact SQ. My point is a hi-quality tube DAC will provide even more opportunity to achieve your goal. Good luck.

If you can spend up to $3k, take a close look at the PrimaLuna EVO 100 Tube DAC online reviews.  Seems to meet/surpass your "musical" criteria as opposed to neutral, detailed, extended, etc.
