Parasound A51 5-channel amplifier. 250Wx5. THX Ultra2 certified. Lots of positive reviews. $5,000 MSRP

Selling for $2,795.00

250W x 5 powerhouse!



The A51 is another John Curl design that shares many similar roots to the 2-channel A23 stereo amp that we just sold. The sonic signature is very similar but with twice the power per channel in 8 ohm (250W in the A51 versus 125W in the A23). In 4 ohm, each channel is capable of 400W! If you don’t want to setup a 7-channel home theater and will be very happy with a 5-channel, then the A51 is just right for you. Loads of power and a sound quality that is befitting of a top class home theater system, the A51 will impress you. Build quality is top notch with RCA and XLR inputs and five pairs of speaker binding posts on its rear panel. Amp weighs a massive 80lb.

Cosmetically, the amp looks really good. Minor scuff marks common with use but nothing major. We don’t have the original box but will securely pack it for safe shipping. Manual is available online.
