If your receiver has pre-outs you can run a two channel power amp to just the front and use the receiver power for all other channels.
When I first started about 8 years ago in college I was very tight on money and bought a pair of B&W 703s (90dB) and ran them off the receiver I already had (and Onkyo rated at 100 watts). At the time I thought it sounded good but I bought a cheap rotel amp (also rated at 100 watts) off of ebay and it made a world of difference.
The speakers had much more bass and improved in almost all areas. It was like I have bought different speakers. With that being said the Thiels impedance curve is much worse and will be a lot harder to drive the my old 703s.
If you want something small that you could tuck away out of sight you could look into class-d amps. They keep getting better... They are small, run cool and have lost of power for the money.
