I'm in the middle of putting together an uber-minimalist system right now as a matter of fact.
Here's the amp I'm getting:

It's a heavily-modified and battery-powered Tripath chip.
The DAC will be a Scott Nixon DacKit (not the tubed one), and it'll go into the same kind of enclosure as the amp, and be powered by the same kind of battery:

Finally, the speakers are Bastanis Prometheus... they're full-range, extremely high-efficiency speakers with no crossover between 100Hz and 10kHz. These are the speakers Peter that Brueninger raved about in Stereophile last month.

Aside from the powered sub amp and my transport (for now...) I'll be completely independant of a/c power. Just can't wait until everything gets here to see how it all sounds.
