Best DAC’S $5k to $15k

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. 

PS Audio DIRECTSTREAM DAC MkII

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

For me it's the Lampizator line.  The Baltic 4, Atlantic TRP, and Big 7 all fit your price range.  The Lampis beat several of the brands listed above.  I went through a LOT of DACs before settling on the Golden Gate.

@audioman58 The T+A Dac 200 is not $6000, it’s $7600. You have misquoted this in a few threads.
