The 9-channel PA-MC5500 is Onkyo’s top-of-the-line power amp, designed to partner a high-end pre-pro such as the recently released PR-SC5507 A/V controller.

As an all-analog amplifier, the PA-MC5500 is built to deliver powerful, well-balanced amplification free from digital noise interference. The precise, high-power performance comes courtesy of components and design features that will impress even the most demanding audiophile.

Onkyo’s trusted WRAT amplifier philosophy ensures low negative feedback and high instantaneous current capability. Meanwhile, customized capacitors, large transistors, gold-plated terminals, and a massive toroidal transformer exemplify the unit’s superb engineering standards. In recognition of this, the PA-MC5500 boasts THX Ultra2 certification: the ultimate guarantee of amplification quality.
