15 GODINA SMO TU ZBOG VAS, UVEK NA STRANI POTROŠAČA I KVALITETA
This amplifier sits above the award winning A-9010 and features 4 x RCA line-level inputs, 2 x coaxial and 2 x optical inputs along with a high quality on board a 32-bit/768 kHz DAC.
Building 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/µs 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.

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 optimised for digital music . 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 “synthesised” feeling sometimes produced by digital processing.
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 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.
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 analogue circuitry. L/R channels are symmetrical to equalise signal path-lengths and minimise stereo playback errors. Coaxial digital inputs, phono input, speaker posts, and RCA line inputs are gold-plated and of excellent quality. Finished with an aluminium front panel and volume control, the A-9150 presents as a component built to last.
Customised High-Current Transformer
Current has great influence on sound quality. High current is required for a better grip on the speaker transducers, improving control and accuracy. A customised 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 aluminium heat sink. Speakers react instantly, with throw-range precisely controlled for accurate articulation even through dynamic and complex musical passages.
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 equalisers served by a top-quality customised head amp, which operates in discrete configuration for MC signals. Together with analogue power amplification, this high-grade phono input design expresses the depth and vitality of music on vinyl.
