The Onkyo TX-8555 is a two-channel 100 watt receiver released in 2008. Equipped with proprietary Onkyo amplifier technology and housed in a sturdy, vibration-resistant chassis. It is compatible with iPod®, SIRIUS™ satellite Radio, XM® Satellite Radio, CDs, and other traditional audio sources. It even offers Zone 2 capability, so users can simultaneously play a separate audio source in a second room. This product is mainly targeted for audio enthusiasts who want great stereo sound but don't need all the bells and whistles of a home theater model. It's suitable for that cozy den or bedroom where users can relax and just listen to music. The most prominent feature of this piece is Onkyo's renowned low-impedance amplifier design. Its oversized, shielded transformer provides impressive power capacity and stability while minimizing hum. This piece costs $100 more than the Onkyo TX-8255 with the only difference being the 100 watts/channel vs 50 watts/channel.  However, it has the same price as the Sony STR-DH700 that offers 7.1 channels x 105 watt/channel.
