Mirror Audio Tubador DAC recommendations

I have an Ayre Codex DAC, a nice upgrade from my Ayre QB-9, and have recently become intrigued with recommendations for the Tubador as an upgrade to the Codex.  I would welcome any input before making a decision on this purchase. Thanks. 

If your going to get it make sure you get all the Upgrade options. Will run you about $2200. There is another thread here on Audiogon with all the info/details about the upgrades
I like the fact that the Tubador DAC has no upsampling.  Presently, I'm using a BorderPatrol DAC SE and it is really good ~ $1595.  I'd certainly look into this one prior to purchase.
