Refined Power Amplification

In 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 SpectraModule™

Discrete SpectraModule boasts a slew rate of over 500 V/μs, 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 Board

The 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 Capacitors

Current 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.

A-9150 Reviews

  • I purchased a 9150 to replace my Onkyo a-7555 which was wonderful. I went to the 9150 mainly for the preamp section and the new technology that it has. I have been very happy with the sound quality of the music and the build. The only drawback that I have found is the power output which tops at 60 watts into 4 ohms. I run hyperion audience speakers which are 4 ohm. The other issue has been the output volume of the otherwise fine phono preamp. I have purchased a Onkyo m502 in perfect condition and it has made a world of difference in the quality and output. I use the 9150 as a pre amp. This is a great combo. I would have given this 5 stars if the unit had greater output wattage[150-250 range] Overall I would recommend this unit .

  • Great sounding amp-I use with dynaudio 4 ohm speakers and they sound great either streaming with Qobuz or cd/sacd from Onkyo c-s5vl player. The technology in the pre amp section is great .Love it. I bought this after 10 years with my a-9555 onkyo amp
