How to choose the best HiFi audio amplifiers?

Enjoying superior sound quality is easy these days, as long as we choose quality products that deliver the purity and power of sound we need. And since the amplifier is one of the key elements in any sound system, with our guide to buying the best HiFi audio amplifier you will have the keys to find the most interesting product for you, according to your preferences.

Shopping guide


The main purpose of any HiFi audio amplifier is to increase the power of the audio signal generated by any device. Therefore, power is the first aspect that we must assess when choosing one of these products. In any case, it should be remembered that a higher power does not mean a higher quality of audio output, as there are other factors that influence this sound.

The first question that we must determine to choose an amplifier is the power that we need. A power that must go hand in hand with the speakers that we have at home or with what we plan to buy. It is always recommended that the power of the amplifier be less than that of the speakers, since if we do it the other way around, those speakers will surely end up being damaged by the excess power and sound generated by the amplifier.

As a reference, the optimal power level would be one that allows us to use only approximately 80% of the power. So if we want to buy some 100-watt speakers, it would be enough to have an amplifier of about 125 watts. And although we are not going to go into the size of the speakers and their power, for reference, these 100 watts would be enough to cover a room of about 30 square meters of surface.

Easy to use

We continue talking now about the ease of use that the product offers us. Something that depends directly on the options that it gives us, since a simple and cheap amplifier with few options is not the same as a high-end model loaded with features. But in both cases, it is necessary that the use be as simple and comfortable as possible.

A use that generally begins with the front panel area. In this panel we should find the volume and tone control, being the basic elements that should not be missing in any equipment. If the model has more options, we will also find the possibility of switching between sound sources, depending on what we want to hear at any given time.

As the model includes more functions, this panel expands its features, so if we already have a lot to choose from, it is worth opting for a model with a screen. This helps to better control the equipment, especially when we have several audio sources or use MP3 playback functions and the like. And to top off the comfort, nothing better than a remote control, which prevents us from having to get up from the sofa when controlling the equipment.


The last aspect that we are going to look at has to do with the connectivity of the product. An aspect in which modern technologies have changed these products a lot, as we can see in any comparison of HiFi audio amplifiers that we see.

As with other devices, this connectivity is split between wired and wireless options. Starting with the wired ones, the connections for the speakers are the first that jump out at you. Connections that have the form of a tab where to place the copper cable of a lifetime, typical of models with an economic price, to more advanced connections in the form of a screw or similar. In this section we also frame the optical output, which is common in higher level models, or the USB ports to charge what you need.

On the wireless side, it is already possible to find amplifiers with Bluetooth connectivity, so that we can use them to reproduce all kinds of content from our mobile or tablet without problems. For this, the same technique is used as the one used by the USB player port. And if you need something else, halfway between receivers and amplifiers, you will have products with the capacity to even move around the network and load radio stations on the Internet. Something that gives greater functionality to the equipment, although obviously it also influences how much the amplifier costs.

Frequently asked questions

Q1: How to clean a HiFi audio amplifier?

The cleaning process of a HiFi audio amplifier is not something that requires more care than we should have with the cleaning of any electronic device. This implies not using aggressive products and being careful so that the liquid does not penetrate inside. For this interior cleaning, if necessary, the use of a brush and a vacuum cleaner or compressed air blower is the most recommended. Although always carefully so as not to damage any component. A process in which it is key to eliminate the greatest amount of residue so that the product has the appropriate sound quality and lasts longer.

Q2: How to build a HiFi audio amplifier?

When building a HiFi amplifier there are many aspects that we must decide. One of them is the type of system we want, given that we can resort to models with valves or solid state, among other options, since all of this influences this manufacturing system. Once you have it clear, you will have to prepare the corresponding schemes, taking into account the need to have sufficient power support for the audio quality you want to obtain.

A process in which, on the net, there are all kinds of plans that will give you more information about it. In any case, we are talking about a complex process and not suitable for newcomers, so in these cases the purchase of a conventional HiFi amplifier may be the best solution. Although you also have kit designs, already prepared, that you can assemble by yourself.

Q3: What connections does a HiFi audio amplifier need?

Leaving aside the essential electrical connection, the HiFi amplifier requires a double output to connect the two speakers that this system generally uses. These loudspeakers are usually connected directly by copper cable, using either the clip system or the more modern and secure screw system. Some models also include line inputs and outputs, depending on the product’s features, although these are present in more advanced models.

Q4: Why does my HiFi audio amplifier blow fuses?

When a HiFi audio amplifier blows fuses it is because there is an electrical problem. It may be due to a punctual power surge, although if the problem repeats, everything will point to a fault in the internal circuitry of the device. In fact, the idea of ​​the fuse is to avoid damage to the product, the fuse absorbing that excess voltage. So if the problem persists, you should take the amplifier to a technical service or check the internal circuitry, if you have the necessary knowledge to do so.

Q5: What difference does a class D HiFi audio amplifier have?

Class D amplifiers have advanced technology that allows cuts and resumes to be executed in the process, thus allowing greater efficiency in the amplifier operating process. Models based on this technology generate greater audio performance with less power, also having more compact sizes than models based on other systems.
