Popular DAC that is known for its warm-ish sound?

Lampi and Luxman off the top of my head...

The specifications for the TEAC 505 look pretty good.   I was discouraged from purchasing a used 505 on the grounds that the unit's documentation would be in Japanese only, and that there are questions about TEAC's customer support presence in the U.S.  I would be interested in hearing about TEAC documentation / support / repair issues with respect to this equipment from Audiogon readers.   

North Star Supremo and Excelsio. The es9016 based DACs from NSD are more neutral but these two are very smooth and engaging. 

I cant believe nobody mentioned Chord. The Hugo series is excellent. 

Another nod can go to the AMR gear. I’d assume the new iFi Pro iDSD would have a similar tone but I haven’t heard it. 

Marantz gear is musical with just a tad bit of bite to it. I’d recommend the HD-DAC1 or the higher end SACD players. 

Any tube based dac should get there but then you might be chasing tubes instead of the dac. 

where can a good lad find a TEAC NT505 for sale in the US of A?
would you say the NT505 bests the RME ADI-2 for sound quality?
I would like the network capabilities

I haven't heard the TEAC 505 yet.  They can be found on eBay and Audiogon.  To be honest, given the prices available, I was going to order one without having heard it first.  A gamble for sure.
