Budget American made speakers?

I am very happy with my Paradigm A2 Shift self powered speakers. You can plug them into virtually any electronically generated device from a guitar to an iPod, to a smart phone and get great sound. I have them connected to my PC via an Essence DAC and the sound is great, whether it is coming from my iTunes, YouTube, or a PC game.  They run about $700 a pair. 

Digital Signal Processing

Sophisticated mathematical algorithms shape frequency response so that even when you're listening at loud levels not only is the bass intense, overall sound from the A2 is unbelievably accurate, clear and musical.

Decware DM-945!!!
 

Klipsch Forte and Marantz 2275 are a match made in heaven and can be pass down to future generations. They're available on the secondary market, but getting rarer.

Not quite a bookshelf, not really a tower.... the Klipsch Heresy III is a great speaker that can be found within your budget. 

I'd say the Vandersteen or Maggies would be a great start.  Both have outstanding pedigree's and will be around for years and years.  The Vandy's just get the music right.
