DAC choices -- help me cross the line

My current DAC is Cambridge Audio Azur 851D driving the two channel speaker system in the study. My headphone system consists of a Bluesound Node 2i feeding into a Quicksilver headphone amp. The plan is to put the CA DAC in the headphone chain and sell the Node, so this means I have to purchase a new DAC for the 2 channel system in the study. Here's what the 2 channel system looks like ...

So what am I looking for? Heft, holographic, a bit of warmth, big organic sound, tonal richness. I don't mind sacrificing a bit of neutrality or accuracy. I listen to all kinds of music but am partial to jazz, vocals, classic rock. 

I almost pulled the trigger on a Mytek Brooklyn DAC+ but wanted to take the R2R DACs for a spin just for kicks. I was initially interested in the MHDT Pagoda or Orchid, but their no-return policy is a no go for me. I know some people don't mind, but I really don't want to give my business to a company who doesn't trust its own products.

So this leads me to three final contenders -- AudioMirror Tubadour iii SE, Tubadour iii (regular/non-SE) and the Border Patrol DAC. Really interested in hearing from someone who might have heard at least one of the two, or better yet compared the Audiomirror to one of the MHDT DACs.

Now Audiomirror offers two versions of the Tubadour III -- SE and non-SE, with the SE being a $1000 costlier. Wondering if the sonic improvements are worth the higher $$$ in the SE version. Would love to hear from someone who has had a chance to compare the two.

Also wondering how the Tubadour III regular version compares to MHDT Pagoda. Both are around the same price.

Note: If are going to suggest another DAC, I don't mind. But please make sure it's R2R, < $2500 (used or new), has a return policy, and NOT made in China.
