Should I get the Ultra Fi DAC 41/Tranquility SE?

I'm contemplating a purchase of either the RWA Isabellina or the Ultra Fi DAC 41, but first I'd like to make sure the 41 emphasizes the traits that I find most important. I'm under the impression that the Tranq SE is somewhere along the same audio signature lineage, so impressions of that are welcome as well.

Would you recommend the DAC 41 to me? My preferred sound signature is a DAC that puts emotional involvement and musicality first (that certain quality that you don't know why, but you just want to keep listening deep into the night), a forgiving sound signature, and meaty vocals. Everything else not listed, like soundstage and details, are of little importance to me. Based on this, would you guys suggest the DAC 41 to me? Or my other frontrunner, the tube NOS DAC RWA Isabellina LFP-V?

Also, please note that I tend to prefer that first trait I listed (emotional involvement to the point of music addiction) far above the others, so if you guys could take that into consideration for me.
