Integrated Stereo AmplifierTake Music Further with True FidelityBuilding on acclaim for the award-winning A-9010, Onkyo again raises the bar for musicality in the entry class with its A-9150 Integrated Stereo Amplifier. Unique technologies coalesce around a refined amplification system to deliver outstanding transient response, superb dynamics, lifelike soundstaging, and nuanced articulation of your favorite analog or digital music.Key to this sense of realism is Discrete SpectraModule, which boasts a slew rate of more than 500 V/micros for flat linearity up to megahertz bandwidth. Rediscover the vitality of analog with MM/MC phono input served by dedicated equalizers on a separate circuit board, with custom head-amp operating in discrete configuration for MC signals.Listeners with big CD libraries will discover new life in the format with AKM's premium 768 kHz/32-bit DAC (AK4452) enhanced by DIDRC Filter, an original circuit technology that cleanses signals of high-frequency noise. Backed by 70 years' experience in hi-fi design, the A-9150 invites you inside the energy of every musical performance.Refined Power AmplificationIn order to deliver a clear and comfortable audio image, it's vital that sounds of different frequencies arrive at the listening position simultaneously.Power amplification circuits feature original topology that's carefully tuned for phase accuracy, wide-spectrum signal reproduction, and natural transient response.Fitted with hand-selected audio-grade parts, the amplifier contributes to lifelike and involving sound quality.Nuanced Musicality Delivered with Discrete SpectraModuleDiscrete SpectraModule boasts a slew rate of over 500 V/micros, significantly higher than competitive products that use a standard IC chip.High-voltage performance enables flat linearity into the megahertz range for full-bandwidth signal reproduction. This is important not only for natural transients expressing the nuances in music with freshness and vitality, but also for accurate definition of instruments ranged around a larger and more realistic soundstage.Dedicated MM/MC Phono Circuit BoardThe A-9150 makes your records sound better than ever. A gold-plated phono input supports signals from either MM or MC cartridges fitted to your choice of turntable.Separate phono circuit board has dedicated equalizers served by a top-quality customized head amp, which operates in discrete configuration for MC signals. Together with analog power amplification, this high-grade phono input design expresses the depth and vitality of music on vinyl.Customized High-Current Transformer and Custom Audio-Grade CapacitorsCurrent has great influence on sound quality. High current is required for a better grip on the speaker transducers, improving control and accuracy.A customized high-output transformer and two huge custom capacitors inside the A-9150 deliver current through discrete output-stage transistors that are kept cool by an aluminum heat sink.Speakers react instantly, with throw-range precisely controlled for accurate articulation even through dynamic and complex musical passages.DIDRC Filter and Hi-Grade DAC for Natural SoundDistortion in the ultra-high-frequency spectrum can have a noticeable impact on the character of audible sound. Even the best D/A converters introduce some noise to the signal, and that noise is amplified, distorting the sound you hear.DIDRC Filter completely erases ultra-high-frequency noise. Performance is optimized for digital music with an undistorted frequency response extending far above the range of audibility.Combined with a premium 768 kHz/32-bit DAC, you can enjoy a greater sense of realism from digital sources, with none of the unnatural "synthesized" feeling sometimes produced by digital processing.Solid Build with High-grade TerminalsA peek under the hood tells you what to expect from the A-9150. Held in place by a flat chassis that tames resonance, the digital audio board is isolated from the analog circuitry.L/R channels are symmetrical to equalize signal path-lengths and minimize stereo playback errors. Coaxial digital inputs, phono input, speaker posts, and RCA line inputs are gold-plated and of excellent quality.Finished with an aluminum front panel and volume control, the A-9150 presents as a component built to last.

I was so impressed with the first one I bought another! For the price, this is the only audiophile level amp on the market. The first one is driving 2 sets of speakers but not at the same time.... set one are vintage JBL L50 speakers and they have never sounded so "open and transparent". These are 8 ohm loads so the 9150 has no trouble driving to levels I prefer. Just barely warm after a couple of hours which indicates to me that all is well! The second set are also vintage Acoustic Research AR9lsi towers which are a challenging load at 4 ohms for any amp. 9150 again performs way past my best expectation with warm, tight, and deep bass frequencies that make you melt. Also open and transparent with a huge and deep sound stage. I forgot how impressive a 2 channel system is with the right equipment.

The just received #2 9150 is burring in at this moment. Currently using as a pre-amp to the infamous Onkyo M-5030. Driving a set of Infinity bookshelf's with a sub for the really deep end. These are 6 ohm loads. Placement on final on this system as I'm having fun experimenting.

I have McIntosh, dbx, Sony, and several other power amps usually driven with Sony ES or Onkyo pre-amps but I'm happy to say the 9150 holds it's on against these heavy hitters.

About the DAC in the 9150.... worth the price of the amp for the DAC alone. You have to hear it to believe it. The warmth of the sound is equal to or better than my Marantz 2275 (analog) which was bought in 1977.  

Lastly, Adorama filled the order quickly and shipped to my door is record time (UPS was delayed by weather) so Kudos to them! I've read the 9150 has been discontinued, hope not but either way I'll be enjoying mine for years to come. Just buy it!

Beats all expectations!

My main amp went out and I replaced it temporarily with an Onkyo receiver (TX-8020; 50 watts). I was really impressed with its sound?for the price?and I thought a dedicated Onkyo amp might sound even better. This one really does. The receiver already had good bass punch, and this adds extra weight too. Overall, the sound is more full-bodied, rounded, and smoother, and less distorted in the treble. The amp is not really any more detailed than the receiver, but it's a high-current amp, with a very heavy transformer and big capacitors, and that means more color, texture, depth, and body. Onkyo has focused on key elements that create high-end sound and brought them together here at a low price. The receiver gave me the clear outlines of the music; this amp fills them in and puts flesh on the bones. The emphasis is on sound quality, not features, but I'm extremely happy that it does include balance and tone controls. Sometimes, listening to really old recordings, or listening at low volume, those tone controls help dial in the right sound, and I think all integrated amps should include them.

Don't use the supplied power cord. An audiophile cord will sound cleaner and smoother. The internal DAC seems fairly good, given the overall price of this package, and it mates well with the amp. But a state-of-the-art DAC like the Topping D90SE (about the same price as this amp) will definitely raise the listening experience further and show what the amp can do. For that matter, you can easily pair this amp with more expensive speakers too and get a taste of high-end sound. Before break-in, the A-9150 may sound dull and thick, but after 20-40 hours it gets more focused and detailed. I am really glad I got this. Since it's been out for several years now it may not be available much longer. Word to the wise.

A high-current amp at a low price

I have had this amp since it came out. I purchased it for the pre amplifier section as it has great features and technology. I run Beyerdynamic Amiron home headphones from it. It runs my Dynaudio audience 52 speakers without problem in near field listening .{ Dynaudio recommends 64 watts for a small room] In larger areas I run thru Onkyo m502 power amp. I use a Rega dac between my imac and the 9150. The dac in the 9150 is very good and I use the onkyo dac with the headphones as I find the Amirons are a slight bit warm as is the Rega dac. We are talking about a subtle difference. stream Qobuz,and I use my imac large alac lossless library as well as cds . I would give this amp 5 stars if it had more power even though 60 watts into 4 ohms should be enough for most people. The m502 amp puts out 220 watts into 4 ohms and does open the speakers up a bit. The Dynaudio are known to need more power and other speakers might be easier to drive. I would recommend the a9150 with out hesitation to all.
