Krympress reports:
The modern audio equipment market offers a wide selection of solutions for lovers of high -quality sound. One of the key components of any audio system is Hi Fi amplifier — A device responsible for transmission of sound with minimal distortions, an accurate transmission of the nuances and a sufficient power to “build up” acoustics. In this material, we will figure out what a Hi-Fi amplifier is, what species are, how to choose a suitable device and where it can be purchased without risk.
What is an amplifier Hi-Fi
Hi-Fi (High Fidelity)-a term denoting high accuracy of sound reproduction. The Hi-Fi amplifier is a component of the audio system designed to strengthen the audio signal coming from the source (for example, a CD player, a vinyl player, a streaming device), and transfer it to an acoustic system with the highest possible quality.
Key features of Hi-Fi amplifiers:
- minimum distortion level (low ThD — Total Harmonic Distortion);
- wide frequency range;
- high signal ratio/noise;
- high -quality element base and circuitry;
- Mostly analog or hybrid nature of the work.
Types of Hi-Fi amplifiers
There are several types of amplifiers that differ in design, the method of strengthening and purpose. Consider the main categories:
Integral amplifiers (integrars)
These are the most common devices. They combine the pre -crew and power amplifier in one building.
Pros:
- Convenience of connection;
- compactness;
- Often are equipped with built -in DACs, Bluetooth and other functions.
Cons:
-
Less flexibility in comparison with separate components.
Separate components: Presenter + power amplifier
This approach allows you to get the highest quality sound, separating the function of signal processing and its amplification.
Pros:
- the best sound quality;
- The possibility of flexible system adjustment.
Cons:
- higher price;
- They require more space and attention when selecting components.
Lamp amplifier
Uses electronic lamps instead of transistors. It is distinguished by “warm” and “living” sound, especially loved by fans of analogy sound and vinyl.
Pros:
- characteristic «vintage» timbre;
- Deep elaboration of vocals and tools.
Cons:
- require regular replacement of lamps;
- more sensitive to load and connected AS;
- High price.
Transistor (solid -state) amplifier
The most common type. It is characterized by reliability and stability in work.
Pros:
- universality;
- higher power;
- stress resistance.
Cons:
-
It may sound less musically compared to tube (subjectively).
Digital amplifiers (classes d and t)
Compact and energy -efficient. A good solution for multi-systems and digital sources.
Pros:
- high efficiency;
- minimum heat emission;
- Small size.
Cons:
-
Some models are inferior in sound to analog brothers.
How to choose a high-quality Hi-Fi amplifier
The choice of amplifier depends on many factors. This is what you should pay attention to:
Compatibility with acoustics
Check that the amplifier is suitable for power and impedance to your acoustics. It is recommended to choose an amplifier with a power supply of about 30% relative to acoustics.
- Impedance (OM): The amplifier must safely work with acoustics of 4-8 Ohms.
- Power RMS (WT/Channel): Focus on a power of 50-150 W/channel, depending on the size of the room.
Sound quality
It is best to listen to the amplifier live in the cabin or from acquaintances. Pay attention to:
- Detail;
- tonal balance;
- dynamics;
- Scene and localization of tools.
The presence of the necessary inputs/outputs
- analog (RCA);
- digital (optics, coaxial);
- USB or Bluetooth (if it is supposed to connect mobile devices);
- Flood exit.
Functions and additional opportunities
- built -in DAC — useful when connecting digital sources;
- The phonorrector is required for the vinyl player;
- Adjusting the timbre, balance, choice of source from the remote control, etc.
Constructive and materials
A reliable case, good cooling, high -quality connectors, a sufficient power transformer (often toroidal).
Popular and respected manufacturers of Hi-Fi amplifiers
Here is a list of brands that have established themselves in the world of Hi-Fi:
Japanese manufacturers:
- Yamaha is a wide range from budget to premium decisions.
- Denon is a recognizable handwriting in sound, reliability.
- Marantz — musicality, a rich history of the brand.
- Pioneer — interesting models with a good price/quality ratio.
European brands:
- Cambridge Audio (Great Britain) — simplicity and musicality.
- NAD (Canada) is a neutral, detailed sound, often with digital inputs.
- Rotel (Great Britain/China) — amplifiers of the middle and high class.
- Arcam — high sound quality, modern approach.
Premium segment:
- Accuphase (Japan) — top equipment, high price.
- Mcintosh (USA) is a legendary brand with a recognizable design.
- Luxman is a lamp and transistor heritage of Japan.
- Audio Research — high -class tube solutions.
Where to buy Hi-Fi amplifier without risk
In order not to get on a fake or poor -quality equipment, purchase amplifiers only from trusted sellers:
Official dealers and chain stores
- “Audiomania” (“Audiomania”), player.ru, dr.Head, all-tools.ru, techport, DNS, M. Video/Eldorado-there are hi-fi departments.
- Before buying, specify the availability of authorization on the manufacturer’s website.
Profile Hi-Fi salons
Shops with the possibility of listening.
Pros:
- the opportunity to listen to before buying;
- consultations of specialists;
- Often promotions are offered, trad-in and sets.
Buying with your hands is careful!
- Check the seller;
- Do not buy wiretaps without the possibility of wiretap;
- Be especially careful with tube amplifiers — they may require replacing elements.
It is worth noting this moment: the choice of high-quality Hi-Fi amplifier is an investment in a comfortable and emotional listening to music. Given the type of acoustics, preferences in the sound, the features of the room and functional requirements, you can choose a device that will give you years of pleasure. The main thing is not to rush, study reviews, compare and, if possible, listen to live. This will avoid mistakes and get the maximum from your audio system.
