Onkyo's TX-8555 A/V Stereo Receiver: Focusing on a Superior Audio Amplification Approach for Quality Stereo Sound

In the fast-paced world of home entertainment technology, change has become an understated word. Technologies now change so quickly that the new becomes yesterday’s product before you barely become accustomed to it. Perhaps it’s time to refocus on what’s really important for quality audio: first-rate sound with high power output. Forget about over-hyped processing technologies. If your receiver lacks the fundamental amplifier design from the power supply through to the output stage, everything else is superfluous. The TX-8555 is built with this in mind. Incorporating Onkyo's proprietary Wide Range Amplifier Design (WRAT) with an isolated power transformer and discrete output stage, the TX-8555 is focused on maintaining the purity of music, radio and video sources. Also, with the option to take up XM® Satellite Radio or to connect your iPod® to the system, the TX-8555 gives you the versatility for a sweeping range of entertainment options.

Superb Design


The TX-8555 includes Onkyo's exclusive Wide Range Amplifier Technology
With its continued excellence in sound reproduction, Onkyo has once again created a powerful, very versatile stereo receiver for the home theater enthusiast. The TX-8555 Stereo Receiver offers superb functionality and dual-room capability that will be hard to match. Onkyo exclusives like Wide Range Amplifier Technology (WRAT), Discrete Output Stage Circuitry, Massive Power Transformer, and Heavy-Duty Extruded Heat Sink offer the cleanest signal on the market. Most of the receiver's audio processing is handled automatically, with little intervention on your part. However, it is so advanced; its discrete output reproduces music with unmatched sonic clarity and dynamic power.

This receiver features a high-end design approach encompassing everything from its massive power transformer design and high-current, low-impedance drive to discrete output circuitry and minimal use of negative feedback. This enables the receiver to combine tighter bass, superb transient response and enhanced presence at any volume level. It's the Wide Range Amplifier Technology (WRAT) that will fill your room with noise-free, impressively powerful, true-to-life sound. With a broader frequency range and lower harmonic noise entering the signal path, this receiver is perfectly suited for new high resolution DVD-Audio and SACD formats.

In a Nutshell

The TX-8555, with high-current, low-impedance drive capability, 2 x 100W amplification, 20Hz - 20KHz frequency response, and a vibration-resistant chassis, is a lot of what you need and none of what you don't. This receiver is capable of delivering breathtaking stereo sound. It features XM/Sirius satellite radio capability, 4-sets of A/V inputs, 2-sets of audio inputs/outputs, Zone 2 output, individual treble, bass, and balance controls, Remote Interactive (RI) port, A/B speaker switching, banana plug speaker posts, and an AM/FM tuner. Because of the high efficiency of its design, this receiver produces exceptional sound quality, and clarity in every audible detail. With speaker A/B selectors and dedicated speaker terminals, this receiver offers the capability to send audio to a second room. In addition, the built-in IR port enables multi-room distribution with optional control systems.

    Great bang for the buck!5
    To say that this Onkyo is a performer for the money is an understatement. I have an Onkyo 705 surround receiver so they were my first choice for my stereo setup as well, but I auditioned a lot of other equipment in the price range, and nothing came close! This is exactly what Onkyo is known for; clean, crisp power, good signal-to-noise ratio, etc. I am using it to power some Bowers and Wilkins bookshelf speakers that have a sensitivity of about 85db, and at only 40 volume, the house is filled with beautiful sound! I would recommend this receiver to anyone looking for the best performance from their stereo system without buying separate components (pre-amp and power amp)!

    The construction is very solid, as with all Onkyo products, and it has a nice weight to it without feeling like it's full of lead. It keeps to the clean, simple component styling that Onkyo and so many other brands are known to use, which I find very attractive. My two main complaints are trivial, but still should be addressed. 1) I could have used a backlit remote like on the 705 and... 2) You have the press the PURE AUDIO button twice to get the PURE AUDIO mode... otherwise, from one press of the button, it goes to DIRECT mode.... Like I said, trivial.

    Value: 10/10
    Power: 10/10
    Sound: 9.5/10
    Construction: 10/10
    Remote: 8.5/10

    Overall: 9.75/10

    Superb5
    After three decades of using Sony products ranging from phones to TV's and stereo equipment, we decided to venture into the world of Onkyo. This receiver had good reviews, fair price and seemed very simple to use. Boy, what a surprise when it arrived: heavy, well constructed, actual knobs for bass and treble, easy on eyes LCD panel, and a boat-load of connections in the back. I'm actually surprised I was able to find a stereo receiver of this caliber.
    The built quality is excellent. Instructions... not necessary and the sound! The sound is spectacular. Very linear, clear and direct. No volume spikes, muddy sounds or any form of "hiss" from this unit. Power is more than enough for an average size living room. I have it connected to a Yamaha sub and a set of old KLH speakers. Both of them emit sound that I've never heard before: clear and punchy. It seems the speakers run more efficiently as well (if that's possible). They don't seem strained or overworked. Overall, a great product and I hope it's as reliable as Sony has been.

    A couple of minor gripes, again in no way do they affect my satisfaction with the unit. 1) Remote... wish it was as basic as the receiver itself, 2) position light indicator on the volume knob.

    Decent audio that won't break the bank.5
    I don't know why it is so hard to find a reasonably priced stereo receiver but after searching high and low for something to replace my Carvin TM 35 amp and preamp I settled on the Onkyo TX-8555. I wanted something that would give me enough inputs along with a phono input that did not cost and arm and a leg and have decent sound quality. After setting up the unit into my Klipsch speakers the sound was different from the Carvin, not bad just different. The Onkyo did not over pump the bass frequencies and once the volume level was set at a comfortable setting, the sound was pleasing. I plugged my Sony DVD player and played a few discs: Beggars Banquet in SACD and Neil Young's Greatest Hits in High Res and both sounded amazing. Regular CD's sounded just as good as through the Carvin.

    This is a basic unit with very basic controls, which is fine by me. The set up time took about 15 minutes. In addition, the price was just right so if you are looking for a decent quality integrated receiver that will not break the bank then look at this.
