$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

If you go the integrated amp route, you might want to consider a Rogue Tempest-III. I think it's around $3,000.
Would definitely go with Wyred 4 Sound. If you liked the Peachtree Dac, you'll love the Wyred DAC. Far superior chip with discrete output.
Wyred integrated and you're set.
What about a Naim Supernait? But I'm not sure if the DAC has a USB input. If not I would buy something like a Cambridge DacMagic with a nice 2nd hand integrated amp. Maybe a MF tri vista or something like that.
6moons review of W4S DAC2 liked the W4S much better than the Peachtree's DAC. If you are playing out of a computer primarily, I'd be sure that you go for an option that has an excellent USB or Firewire implementation. At $1500 the Wyred would certainly qualify, with its async 24/192 USB implementation. Weiss firewire DACs also come to mind, but might be tough to fit into your budget.
Considering what you want to do and your budget, a high quality DAC with volume control directly to a power amp would most likely work very well for you. Some of the previous suggestions of Bel Canto and Wyred4Sound are along the lines of what I'm thinking. I haven't heard the W4S setups, but I am a Bel Canto dealer and use this approach in my system as well (although I'm not using USB as you mention in your original post). Good luck.
