DAC's, i'm lost


I recently purchased a pair of PSB Synchony two speakers along with an NAD 375BEE amp from my local dealer. My audio source is currently my laptop/an airport express. I'm looking for suggestions with DAC's. My budget is 500 and can be persuaded to spend no more than 1000. Please, help a newbie figure out what would work best!!!

Eastern Electric Mini Max $750.00.

MHDT Paradisea Havana $600.00.

Audio Mirror Tubadour Mrk II $1000.00.

Good Luck, Lets us know what you do.
I have the Moon 100d ($599) and am very happy with it. The other I'd be looking at is the Wyred 4 Sound DAC-1 ($999), if I were to spend more. But as others have said, lots of choices.
I agree with Sonnyyoung and also recommend

the Tranquility DAC with a Ridge Street Audio Poiema or Alethias USB cable or the dbauidolabs The Essential USB cable.

Morrow MAP4s wouldn't hurt either to make the connection to the preamp.

I cannot imagine you wouldn't like the Tranquility.

One important thing, think about the power cord used to feed the DAC... affects things more than you might imagine!

:) listening,
