Reco for a low power amp to try


I am just curious about the low powered (those 5W to 12W per channel) amps and how they sound.....
Don't know any retailer in my area that would lend me one for a weekend but if I was to just buy something here and in worst case re-sell here....what would you recommend for starters ?
Hopefully something under $2,000 used....so at first I get a sense of what 5Watts sound like....

My main concern is that I do listen to lot of prog rock (ex;  Pink Floyd) and I do like to up the volume sometimes...

PS: If you happen to live in the NJ area and would be so kind to allow me to try one out - I would be so thankful

Decware...  offerings from 2 w to 60 w....  what are you using for speakers?  That is the main factor along with room size and volume requirements.
No good without speakers of 95+ sensitivity! I have Klipsch Heresy's to use with my Will Vincent SET 45 amp. A mere 1.75 wpc! Yet a good match with the Heresy! So for low power amps the speaker choice is most important!
