$4000 to Spend on Amp, Preamp and USB DAC

So the title pretty much says it. Here's the proposition; Starting from scratch, for $4000, what is your idea of the best sounding pre-owned three component system (amp, preamp and USB DAC). The DAC or DAC/PRE will preferably have HT Bypass and definitely a remote). I listen to Rock, Pop, and Female Vocalists, and like to follow a driving bass line. Bottom Line; it must transport me to another dimension when I listen to my well recorded favorites. :)

Speakers - still the Dynuadio Contour S3.4
Cables - OCOS II
Interconnects - Anticables with Eichmann Bullet Plugs
Power Cords - Magic Power 1 meter
Source - AIFF files through iTunes
