What Is A Stereo Amp?
An amplifier (Power Amplifier) is an electronic component that increases the power and voltage of a signal, that is, makes it stronger. In car audio, this device receives the low voltage signal (from an auto-stereo, crossover, equalizer, epicenter, etc.)
The amp-woofers, subwoofers, speakers, tweeters, etc.) so that they can be heard louder, there are also preamps that are used to increase the voltage that comes out of the car stereo. The amplifier increases this signal to be able to move the speakers.
Integrated vs. Pre/Power Amps
An integrated amplifier is a component that has two devices in its interior, a preamplifier -a kind of switch that allows us to choose audio sources and have a volume control- and a power amplifier -the electronic stage that is responsible for "enlarging" the lowercase signal delivered by the audio sources.
If an AM-FM radio tuner is added to this, it is called receiver. So far, an amplifier of the seventies could be very similar in design to one made in 2016. In fact, we are not few, I included, that we love vintage equipment, which can be continued using and integrating the current concept of Hi-Loyalty.
RMS vs. Peak Wattage
What is the RMS power?
It is an incorrect expression that derives from the usual way of calculating the power of a speaker, which is dividing the RMS voltage squared by the impedance (V² / Z). RMS stands for root-mean-square, which is related to the mathematical transformation that obtains the mean of the absolute value of an alternating signal (that is, with a negative and positive cycle). The appropriate expression for "RMS power" is average power. The relationship between the RMS value and the peak value is different for each signal.
The watts or watts are the power measurement of a speaker, but you must tread eye when buying and look for the manufacturer specifies whether Watt peak, RMS, the program, maximum, musical, AES or other. Saying only that a speaker has 100W is like saying that a ladder measures 1 unit of measure. If it is not specified if this unit of measurement in centimeters, meters, millimeters or whatever the measure is of little use.
The manufacturers of loudspeakers establish some performance tests to measure the power of the same and according to the test they do to the speaker is when they specify if the watts are the peak, RMS, etc.
Peak Watts, Peak Power or PMPO (Peak Music Power Output)
This value establishes the maximum point power (the maximum power peak) that a speaker admits without breaking. This measure does not serve much since the loudspeaker does not support this power continuously and sometimes sellers use it as a sales claim to be much higher than the average value or RMS.
DACs are digital-to-analog converters. Your voice will exist as ones and zeros until you pass one of them, then turn into electrical signals used to power the speakers and then emit a sound. You need one of them. The good news is that your audio source may already have some, especially if it reads a laptop, tablet, phone or CD. Bad news? These may not be very good and maybe worth investing in a separate CAD.
All the amps on our list have and haven't an integrated DAC. Be sure to check before you buy. If we had to choose the best DAC amplifier, we would probably choose something like the Halo Indian-6 Parasound, which offers excellent conversion. This is not our favorite amplifier, but it is quite acceptable.
Stereo Amp Classes Explained
Do not stick to different amps. Class T, class AB, although it is always useful to know the difference between the tube, the monobloc, etc. - and we highlighted some differences between the models - the quality of the amp is high enough that you can now comfortably forget your purchase decisions. Your amp selection should be guided by the number of channels you need, your current setup, the resources, and the space you own.
That said, it's always good to know that sort of thing. In short, here is an example of some of the most common jargons.
A common type, where both output stages are always on. This means in practice that the distortion is very small, even if the amps are not very effective.
A type in which only one output stage can be activated at a time, which improves the energy efficiency at the expense of sometimes adding distortion to the crossing points between the frequencies.
Class A / B
As you may have guessed, this is a hybrid of the two types above that maximizes the benefits while eliminating the inconveniences. Amplifiers with this circuit are relatively efficient and have limited distortion. The Cambridge Audio CXA 80 is a good example of this type.
A type that uses active transistor switches. The electrical explanation is a little complicated and it is the following: Class D is very efficient and is often smaller and lighter than other models. They do not run as hot. Note that if you see the T class anywhere, it is a variant of this type, created by Tripath. You will not find much - the old Orb Audio Mini-T, now abandoned, was one of the few in this class.
Something you will see often in more expensive models. Generally, only one amp powers both channels, but in monoblock systems, each channel has a separate mono amplifier. More power, better sound. There are no monoblocks on our list.
Sometimes called valves, these tiny glass bottles are responsible for the soft, squidgy heat that characterizes some amps. This is not a typical feature of stereo amps - they are usually found more frequently in headphone amps - but they sometimes appear.
A channel is a single audio source; For example, your iPhone will be a single channel (yes, we know that an iPhone can play in stereo, but we work with us here). The circuitry needed to handle a single channel sound is not that complicated and you usually do not pay for high-quality components in cheap amps with fewer channels. It's a sum of stereo and stereo amp means two by definition. However, you can have models with more than two channels, which allows you to add multiple speakers and subwoofers. Of course, we recommend doing so because it will broaden and deepen your voice. We will detail the subgroups below.
When you start adding channels - even if your audio setup is a bit complicated - you'll do it very quickly - things change. Suddenly, you look at things like digital-to-analog converters, special tubes, and valves, or even chillers in big amps. All these components color the sound, give a nice character and you will soon see that you pay for the sound as well as for the original material. Not to mention these options, a good amp will help you control the sound; We expect to find equalization sections and other filters to allow you to customize the sound in your own environment.
THD vs. SNR vs. Crosstalk
One of the things that amplifier manufacturers like to do is choke you with statistics and features without telling you what they really mean. This means that navigating the technical details of an amplifier can be a royal pity for your neck! At TMS, we are interested in such things.
Therefore, we will break some of the most hidden features you will see on the manufacturer's web pages. The good news is that for most people it is not necessary to simply take them into account. We did not mention them in our comparison table above. Audiophiles will certainly take care of them, but things like wadding are often more important in determining whether an amplifier will fit into your setup.
Total Harmonic Distortion (THD)
Sometimes called THD + N (N means Noise), which measures what the amplifier does when it comes to the amplifier, ie it goes to the amplifier. Of course, if you do not mind things like tube amps, you want some color, you want that number to be as low as possible. The good news: it is! In almost all cases of modern amps, the THD is practically low.
An excellent example: the anthem STR with a THD + N value of 0.02%. When someone tells you that THD is very important for measuring the quality of an amplifier, we have the right to make fun of them. If the THD does not exceed 1%, you can ignore it safely.
Signal to noise ratio (SNR)
In addition to music, each amplifier produces a bit of sound. As a result, they consist of electrical components that sometimes make noise during operation. The signal to noise ratio measures the decibel of the amplitude of this noise - or more precisely of the amp. Conversely, the higher the number (measured in decibels), the better the signal-to-noise ratio. Again, you can safely ignore it, because if an amplifier has a signal-to-noise ratio bad enough to indicate, it will not be added to our list.
We have already talked about amplifier channels, and the mix measures how much an amplifier distinguishes the sound from the channels. If that makes the thing bad, you can not choose stereo separation and things get mixed up. Like the RSB, it is measured in decibels, with only the minus (-) sign in front. The larger the number behind the minus sign, the better the stereo separation. It's a little more important than SNR and THD + N, but just a little bit.
Adding Subwoofers To A Stereo Amp
We talked about it in a previous section, so let's go into more detail. All amplifiers in this list will not be configured to handle the submarine. Like Peachtree Audio's nova300, it has a hidden output for the subwoofer and can be thought of as an amp with 2.1 functionality, not a true stereo amplifier.
Technically, you do not need a subwoofer. There is no need for every listening setting, and there is not even room to have. But our decision is to choose an amplifier that will always be better with your low end filled with a special system that you can overcome if you have space and your budget. The good news is that you will not have to worry about the amplifier that powers the subwoofer. In 99.9% of cases, the subwoofer is powered by the network and you just need to direct an audio signal with a simple RCA cable.
Stereo Amp Weight Explained
Normally we do not care much about the weight of equipment. After pressing the masseur to be aware of the bill, it is good to know, but not necessarily. The amplifiers are a bit more complicated.
In simple terms, good amplifiers rely on good power management and equipment is usually heavy to handle power well. One of the easiest signs of a good amplifier is that it bends when raised. Pro-Ject Audio Compare the nova300 Peachtree Audio, a number with MaiA, to a number from our list. Last weighs 4lb, old clock at 17lbs Guess which has the best power management? However, the new power supplies and lighter components make this rule much less rigid and faster than before. As far as power amplifiers are concerned, this is still quite valid, but for integrated amplifiers, you can see it more than any other 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. Anyway, it should be remembered that a higher power does not mean a higher quality audio output, because there are other factors that influence this sound.
The first question we must determine to choose an amplifier is the power we need. A power that must go hand in hand with the speakers we have at home or what we have planned to buy. It is always recommended that the power of the amplifier is lower than that of the speakers since if we do it the other way around, surely those speakers will end up being damaged by the excess power and sound generated by the amplifier.
As a reference, the optimum power level would be that which allows us to use only 80% of the power, approximately. So if we want to buy 100-watt speakers, it would be enough to have an amplifier of about 125 watts. And although we will not go into the size of the speakers and their power, as a reference, these 100 watts would be enough to cover a room of about 30 square meters.
Easy to use
We are now talking about the ease of use offered by the product. Something that depends directly on the options that the same gives us, given that it is not the same a simple and economic amplifier with few options than 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 in the area of the front panel. In this panel we should find the control of volume and tone, being the basic elements that must 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 each moment.
As the model includes more functions, this panel expands its features, so if we already have a lot to choose from, it is worth choosing a model with a screen. This helps to control the equipment better, especially when we have several audio origins or use MP3 playback functions and the like. And to top off the comfort, nothing better than a remote control, which avoids having to get up from the couch when it comes to controlling the equipment.
The last aspect in which we are going to focus has to do with the connectivity of the product. An aspect in which modern technologies have changed a lot to these products, as we can see in any comparison of HiFi audio amplifiers that we see.
As with other devices, this connectivity is divided between wired and wireless options. Starting with the wired, the connections for the speakers are the first to be obvious. Connections that have the form of the flange where to place the copper wire of all life, typical of the economic price models, 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 load 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 without problems from our mobile or tablet. For this, the same technique is used as the one used by the USB player port. And if you need something more, halfway between the receivers and the amplifiers you will have products with the capacity to even move around the network and upload radio stations on the internet. Something that gives more functionality to the team, but obviously also influences how much the amplifier costs.
Best Stereo Amplifier FAQs
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 be careful so that the liquid does not penetrate inside. For this interior cleaning, if necessary, the use of the brush and the vacuum cleaner or compressed air blower is the most recommended. Although always careful not to damage any component. A process in which it is key to eliminate the largest amount of waste so that the product has the appropriate sound quality and lasts for 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 since we can use models with valves or solid state, among other options, since all this influences this manufacturing system. Once you have it clear, you should develop 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, in the network, there are all kinds of plans that will give you more information about it. Anyway, we talk 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 ready-made kit designs, which 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 usually used by this system. These speakers are usually connected directly by copper wire, using either the clip system or the more modern and safe thread system. Some models also include line outputs and inputs, depending on the functions of the product, although they are present in the most advanced models.
Q4: Why does my HiFi audio amplifier burn fuses?
When a HiFi audio amplifier burns fuse it is because there is an electrical problem. It may be due to a point voltage rise, although if the problem repeats, everything will point to a failure of the internal circuitry of the device. In fact, the idea of the fuse is to avoid damage to the product, absorbing the fuse 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 HiFi class D audio amplifier have?
Class D amplifiers have an advanced technology that allows cutting and resumption of the process, thus allowing greater efficiency in the amplifier operation process. The models based on this technology generate a higher audio performance with less power, also having more compact sizes than the models based on other systems.
After reading the thorough researched-based guide on best-integrated amplifier review for less than $ 1000, choosing the right amplifier for your needs is not so difficult or so complex. Just start by determining the devices you want to connect, from source devices such as Blu-ray and DVD players to the type and number of outputs such as the subwoofer, headphones, and speakers.
It's always a good idea to buy an integrated amplifier with enough connectivity options to keep up with you over time. Whether you plan to use it as background music for your desktop, video games, streaming music or home theater system, an integrated amplifier will save you money and space while offering an excellent sound for many years.
