For professional sound producer or musician, an amplifier is already widely known but for beginners, they might not know what and how it works. An amplifier is an electronic device complementary with a loudspeaker, it’s used to amplify electric guitars and other musical instruments to increase the amplitude of electrical signals, used chiefly in sound reproduction. An amplifier’s job is to turn a tiny electric current into a larger one with various different ways to achieve this depending on exactly what you’re trying to do.
Amplifier is essential in sound production, it helps to control the sound input and output which then provide result based on how you control and manage it. Today we’re going to discuss about Onkyo A9050 and Yamaha A2501.
The A9050 is a combination of both classic analog power and the latest in digital audio processing technology. For $526.30 and weigh in 8.2 kg, you can feel the mellow glow of vinyl or experience your computer-based library with proper hi-fi sound, A9050 is able to do both. There are three digital inputs linked to a Wolfson® 192 kHz/24-bit DAC, which allow you to exploit the potential of lossless formats such as WAV. Of course, digital inputs are also supported to let you play everything from your computer’s iTunes collection to movie downloads with power and precision beyond anything you’re used to from your PC’s speakers.
With gold-plated audio terminals and gold-plated banana plug-compatible speaker posts, A9050 ensure a perfect connection for your CD player, tuner, and loudspeakers. Featuring low negative feedback with Wide Range Amplifier Technology (WRAT) design, Onkyo A9050 provide naturally vibrant sound which add energy and vitality into recordings. Onkyo developed the WRAT suite of technologies to improve the clarity and character of amplified audio. The technologies work to reduce noise across the frequency range, guaranteeing a clear, balanced, and natural sound. It achieves this by employing a low negative feedback amplifier design, preserving the essential energy and life contained within the recording. Using closed ground-loops, A9050 work to cancel unwanted noise from individual circuits and by enabling high current flows, it can cancel reflex energy from the speakers.

Onkyo A9050 features Dynamic Intermodulation Distortion Reduction Circuitry (IDRC) to eliminate digitally generated noise beyond the normal range of human hearing, frequencies above 100 kHz are susceptible to digital clocking-signal pulse and other forms of subtle distortion. Noise in the super-high-frequency range can affect the character or atmosphere of the original sound, A9050 works by reducing distortion in the superhigh-frequency range to deliver audio clarity. Unlike some other hi-fi, Onky A9050 uses the same Three-Stage Inverted Darlington Circuitry technology which boosts current flows and reduces distortion. It uses in its highend A/V receivers. This innovative circuit topology facilitates high speaker-driving power, reduces distortion, and preserves the buoyancy and expressiveness of recorded music, a unique characteristic of our low negative feedback amplifiers while some others take a shortcut to amplified audio with the use of all-in-one IC chips which compromised the sound once you turn the volume up.
No need to worry about getting your amplifiers too hot as the A9060 has discrete output stage circuitry which means it has cooler running temperatures with receiver’s ability to deliver high power into low impedances is a vital factor in its performance. If the current flow through the amplification circuit is inconsistent, audio quality can be compromised. Onkyo A9050 amplifiers feature separate high-quality components at the signal output stage. Discrete transistors help guarantee a consistent, stable supply of current to the speaker system for an open and assured performance, with less chance of distortion and cooler running temperatures.
Additionally, Onkyo A9050 features Phase-matched bass boost for deeper bass and a clearer mid-range from the warm low notes produced by a cello to the deep frequencies of electronic music, a good amplifier should be able to deliver plenty of bass without distorting. Some amplifiers are prone to the effects of phase shifting, which can overwhelm middle frequencies and muddy the overall sound. The Phase-Matching Bass Boost technology effectively preserves mid-range clarity which allow vocals and strings to shine while maintaining a smooth, natural bass response at all volume levels. The A-9050 features 96 kHz/24-bit optical and coaxial inputs which can carry digital audio signals from source devices such as computers or laptops with a power supply that can maintain or increase output power as required which means that you have deep, powerful bass, wide-ranging dynamics with musical peaks that sound composed and correct timbre and sound staging. When paired with a set of quality loudspeakers, Onkyo A9050 have the capability to drive them with ease. All those features work in combination to enhance the power and fidelity of your audio sources and shape the outputted audio signal. Read also: Yamaha RX A2080 vs RX A1080.
When it comes to sound production, Yamaha is already widely known for their high-quality products. And with this AS501, Yamaha offers high sound quality circuit design based on the ToP-ART (Total Purity Audio Reproduction Technology) concept, it ensures optimum sound when processing and transmission of the audio signal, it is simple, direct and there is less chance of it being affected by noise and distortion. Priced at $549.98, AS501 features an input to output direct symmetrical design with left and right channels organized in a straight, symmetrical layout for highest signal purity. In addition, the ART (Anti-Resonance and Tough) base bottom chassis and a solid center bar provide high-rigidity support and vibration damping. These Yamaha design innovations contribute to this amplifiers’ rich audio reproduction with abundant musicality.
For outstanding audio performance, AS501 custom-made the power transformer and block capacitors with two direct signal path speaker relays, one-point grounding system, aluminum-extruded heat sinks and other top-quality parts which effortlessly handle demanding audio signal conditions. Yamaha AS501 uses high quality parts, carefully selected and tested to provide the quality of each individual part, as well as how they work together determines the sound quality of any component.
