Wifi-based solutions c/w/should give better bandwidth/sound quality than bluetooth.
Are there space/size considerations to take into account?
If not, a stereo receiver, a Phorus PR5 and a pair of decent passive speakers can all be had for under budget.
Here's a comparison of stereo recievers with a basic and upgraded recommendation.
A Phorus PR5 allows for wifi streaming, bluetooth w/AptX and FLAC playback from network drives
There's currently a sale on Jamo speakers currently at several sites. You can find the best ones via slickdeals.net
If you're OK with a non-black color, the S 803 bookshelves, and the S 807 and S 809 towers are the best deals.
You can compare and even "listen" to them at Crutchfield if you have a set of headphones that they calibrate for.
Crutchfield has a pretty generous $10 return policy for speakers if you don't like them.

I also own a variety of headphones.
I won't have a stationary PC though (that's also in a container) so I was wondering what can be had for around $500 for an ideally wireless two channel system that sounds good at low volumes? Phone has aptx HD and most FLAC files on an SD card (hooray for extensible storage)
Must be available in the US ...
