Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at (540) 786-2777 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

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.

DIDRC Filter and Hi-Grade DAC for Natural Sound

Distortion 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 Terminals

A 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.

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.
