Onkyo A-9555


It would be hard to beat this amplifier for the price. The remote works with other Onkyo components, such as the DX-7555 CD player, and the unit is compatible with the Onkyo Remote Interactive Dock, which allows docking of other devices such as the...

Onkyo A-9555 Amplifier


The look is oh-so 1975, but inside, Onkyo's A-9555 is very twenty-first century. Specifically, the amp features the company's new VL digital technology, which Onkyo claims uses a unique implementation of class D amplification that cancels the...

As I finished up with vinyl, I noted that the A-9555 sounded, well, more analog than digital. I played an advance test pressing of Michael Powers's Onyx Root LP from Sterling Sound. Powers's take on the old Sir Douglas tune, "She's About A Mover"...

Onkyo A-9555


Of similar dimensions and not far off in price, this unit looks like a completely head-on competitor to the NAD C372. Internally, though, there's a substantial difference in that Onkyo's chosen amplifying technology is 'Vector Linear Digital'...

Characterful with a strong Bass

A lack of insight into the sound

There are no obvious nasty habits but it is harder to connect with the music than you'd want

First Class product at affordable price


This unit replaced a well regarded integrated amp I owned for many years. This amp has some really nice features that enhance it\'s usefulness, for example the selectable straight through sound path, the sophisticated volume control that avoids running...

this is good stuff


I am very impressed with this dedicated amplifier, as it tests the speaker leads before sending signal down the wire (the gain control knob will flash a light telling you something is wrong on start up). This is powerful stuff ... ALWAYS ... set your...

Onkyo A-9555 - (Integrated Amplifiers)


Product Specifications

Digital amplification enables significant power efficiency savings and supports smaller, more compact designs - obvious benefits for today's home lifestyles. However, at Onkyo, they believe that these benefits should not come at the expense of the most important consideration: sound quality. With the A-9555 integrated digital amplifier, sound quality takes precedence over all else. By using Onkyo's exclusive Vector Linear (VL) Digital technology to remove any spike noise before it introduces errors into the inversion timing, it is possible to get a highly accurate analog-to-digital conversion. Also, at the heart of the A-9555 is a Pure Stream Power Supply - essentially a large power transformer - that ensures that you always have the on-demand power for the clarity and detail of a range of musical genres. By integrating the fundamentals of audio amplification with the potential of digital amplification, the A-9555 is a revelation in superior audio reproduction.
