Onkyo build and develop some of the most highly regarded AV receivers on the market today, being one of the few brands who focus on sound quality and functionality without compromising on either aspect. The company's range of home-cinema hubs are built into a variety of price points, meaning there's a unit for everyone, and each of these units in each of these price categories tend to win awards and hearts alike.

While the PA-MC5501 does offer an uncompromising level of power and efficiency, the unit is designed with a certain amount of intelligence and isn't just all brawn no brains. It's been engineered not only to power loudspeakers efficiently, but to deliver a truly superior dynamic response with an astonishingly pure signal quality. Onkyo's Push-Pull amplification and WRAT suite allow the PA-MC5501 to operate with a minimal interference, stable voltage and a boosted current across the entire electrical system of the power amp. 

Sitting inside the power amp's sturdy cabinet are a number of high quality components, such as the large toroidal transformer, large capacitors and heavy-duty transistors. All of which are designed to handle very high loads. Gold played speaker terminals and XLR inputs allow for a quick and secure, audiophile-standard transmission between signals. This results in an instant signal gain response, phenomenally low levels of distortion across the entirety of the dynamic range. The sound that the PA-MC5501 is capable of reproducing reflects more closely to premium end analogue amplifiers, complete with a soft warmth and beautiful clarity. 

When combined with Onkyo's matching pre-amplifier, the PAMC5501's nine channels and bi-amping capability allows for a truly superlative experience.
