Parasound HCA-1000

This John Curl-designed amplifier brings out all the subtle details of your music, yet still has the punch for the boldest crescendos and home cinema special-effects explosions. I give it a 7 out of 10 due to the small nicks at the top of the faceplate (see photos). It comes in the original factory packaging, and is from a non-smoking household. Shipping is estimated at $100, but may be cheaper depending on your zip code. Feel free to contact me for a more accurate shipping quote.
