Best DAC’S $5k to $15k

At $13,500 I don't think a better DAC can be had than the Mola Mola Tambaqui DAC. Most reviewers and critics have concluded one has to spend > 50K to get anything that sounds nominally better. 

The world needs a new DAC shoot-out!

I will add this.  If a DAC has a top quality volume control/preamp it can eliminate a component.  Not all DAC's have this ability.

spending even 5K, much less 15K is no guarantee that you will get superior sound to a DAC costing under 1K
