What is the best DAC ever made?

Burwin Bobcat?

Bearotti, I don't believe their is one "BEST" DAC ever made, however if you want alot of information regarding reference DACS I would recommend you go to a thread I started entitled, Reference DACS: An overall perspective, that you would find very interesting regarding this topic.

I'm sure it is far from the best, but I'm using a new Audio Aero Prima SE DAC with the upgraded caps and cryoed tubes ($5.7K) via a Siltech Golden Ridge G5 digital cable from my Sony SCD-1 and it is pure magic. Nicer than the Capitole MKII I used for redbook before it. The preamp section is also good. I run the sacd of the Sony through it.
