$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

Thanks everybody. Some excellent suggestions here! I have a USB to S/PDIF converter already from M-Audio.... Interesting idea/suggestion Edorr. That would indeed broaden my choices of high quality DACs. I think the route I am going generally, is the Dac with volume control (i.e. DAC/PRE) plus high powered (minimum 200 wpc into 8ohms) SS power amp. Bought and returned some Odysseys.... Still not sold on the ICE amps... Emotiva XPA2 anyone? Can a power amp for under $1000 really compare to the $4000 amps out there? Many Emotiva owners say yes... Then I could go out to dinner a few more times this year.
Audition a new April Music Stello i500 integrated amp with built-in DAC. Not only would you be hard-pressed to buy used components to equal it, you save the cost of two pairs of interconnects.
Johnny - that April Music piece looks fantastic! But ahh... the conundrum... to integrate or not to integrate?? That is the question.

UPDATE: I ordered a pair of Emotiva XPA-1s today ($2000) which I can audition for 30 days risk-free. That's 1000 wpc into 4 ohms -- and a total of 160 lbs of metal. Yikes! I also ordered a W4S DAC-2 for $1500, and a pair of Acoustic Zen Reference Matrix II balanced interconnects for $380. Total cost: $3880. Now wouldn't it be nice to get this type of performance from one stylish piece like the Stello i500? I honestly have no idea which would be better sonically. But I sure know which would be better ergonomically!

Perhaps I should audition it as well.
For a complete integrated approach, I haven't heard anything better than the Naim Uniti. I mentioned it earlier. If you have a Naim dealer nearby, it's a must audition IMO. Every review raved about. I usually take reviews with a golf ball sized grain of salt, but they're dead on with this product.
Kbark- Thx for the recommendation but I can't deal with the low power rating of either supernait or uniti.
