Product Description

The A-9050 Integrated Stereo Amplifier offers the best of both worlds-classic analog power and the latest in digital audioprocessing technology. Whether you're transported by the mellow glow of vinyl, or just want to experience your computerbasedlibrary with proper hi-fi sound, this is the amp for you. There are three digital inputs linked to a Wolfson 192 kHz/24-bit DAC, which allow you to exploit the potential of lossless f ormats such as WAV. Gold-plated audio terminals andgold-plated banana plug-compatible speaker posts ensure a perfect connection for your CD player, tuner, and loudspeakers.However, it's the sound quality that really puts this amplifier in a league of its o wn. Our low negative feedback WRAT designbreathes energy and vitality into recordings that can otherwise seem lifeless and flat. As well as DIDRC to eliminate digitallygenerated noise, the amplifier's Three-Stage Inverted Darlington Circuitry boosts current flows and reduces distortion.Plenty of good clean power-and a dash of Japanese audio innovation-has resulted in a stereo amp that's shaping up tobecome a new Onkyo classic.

Now, the good: The build quality is excellent.
Having always liked Onkyo sound, preferring it along with Denon over Sony and Marantz... I wasn't surprised I liked this amplifier.
John Steven
I like the fact that it has digital inputs, I can stream my digital music using airplay on my Apple TV.

I purchased this product to replace an ADCOM GTP-500II/GFA-555 pre/amp combo. My housekeeper moved one of my B&W speakers and shorted one of the channels on the GFA-555. The repair would be over $300, so I decided to downsize a bit and go for a modern integrated amp.

First, the bad: I cannot understand why the gorgeous silver version of this unit is not available to US customers. It is a knockout! That being said, the stenciled markings on the faceplate are difficult to read on my black unit, and there is no LED indicator on the volume knob! Also, there is no way to select the inputs directly via the faceplate or the remote - you need to press the input button on the remote or twist the input knob on the faceplate repeatedly until you get to the desired input.

Now, the good: The build quality is excellent. The aluminum faceplate and volume knob look great and feel good to the touch. The ergonomics are just about perfect, with the controls very easy to use. The amplifier section sounds crisp (almost thin), with plenty of top end sparkle. Bass is clean and driving at all volume levels. There is no compression as the volume knob is turned past the 12:00 o'clock position as I have heard in many (even high-end) receivers and integrated.

The built-in DAC is very good sounding and very convenient for connecting a TV and other digital sources. It is not warm by any extent, but neither is it harsh. Still, I preferred the sound of my Sony SACD player using the analog inputs over the amp's DAC. Sound is fantastic when connecting a PC's SPD/IF output to the amp's DAC. Definitely and improvement over using the sound card's analog outputs.

The only real disappointment is the phono stage.

Very pleased that I made the switch from the Cambridge 651A, as this unit's 24 bit Wolfson makes streaming Pandora, Spotify and the like sound much improved. The remote is terrible, however you should be using a master one anyway.

Sound quality: Very crisp details, bass is a little muddy when running direct mode through my Polks. However, I found setting bass between 10 and 11 o'clock is ideal with phase matching enabled for a living room with hard wood floors and the Polk RM passive sub I'm running. I suspect this muddiness I was hearing at 12 o'clock is being compounded from the floor resonating. Treble at 2 o'clock suits my ear best (probably due to some ear damage from live shows over the years).

Conclusion: Great unit for setting up streaming content via the optical, also TV and movies work well. The bass is a little sloppy at default/direct settings, however the tone controls set very effectively. This default bass issue can be expected from the speaker/room acoustics I have, so no fault on the amp. Phase matching (aka loudness) is very clean and does not bleed into the mids. After proper calibration, this amp sounds great and is a steal at $499.

I bought this amp to compare with my yamaha a-s500. They are both great. A feature i really like on the onkyo 9050 that i was initially skeptical of is the phase matching bass button. i call it the bass magic button. It brings to life all the lower frequencies without sounding bloated. On the yamaha i really like the variable loudness knob. The onkyo runs a lot hotter than the yamaha. Overall the sounds of these amps matched with there cd players make it tough to pick which is better. the onkyo 9050 and 7030 cd player run significantly cheaper right now. Either way they are solid choices. The important thing to note is that integrated amps crush hometheater receivers that i have heard. So buy one.

I decided to take the jump back from home theater to go for superior 2-channel audio when I found I was listening to more music than firing up the surround sound. I replaced an Onkyo 5.1 receiver and upgraded my Polk R300 front channels to a pair of Polk Monitor 60 series II, kept the Polk sub, and hooked up digital from sat and blu-ray..kept the analog input from my Onkyo single disc cd. I thought my Onk receiver did a nice job with straight audio...but this amp is the real deal. I'm an old dog audio salesman from the '70s, when Phase Linear, Marantz, etc ruled the world with the huge discrete amps...this little guy, especially at the price, reminds me of the sound from that golden age of audio. If you want straight up stereo, don't want to spend 4 digit money, and are filling up an average size room, go for it. You wont be sorry..it's taken every genre of music I could throw at it and sings crystal clear.

Replaced a Sony A/R with very noticeable improvement in audio to the same speakers (to my older ears). I was actually surprised at the sound quality difference. Sensible audio controls (the Sony required digging through menus to get around presets). Only minor complaint compared to the unit replaced would be that the input selects cannot be labeled (digital inputs and analogue have differently colored LEDs, but otherwise you have to remember which input is for what). Highly recommend if you're in the market for a pure amplifier for analog and digital sources.
