The basics: what makes a Hi-Fi system?

According to the Sound Organization, there are three basic components that make up a Hi-Fi system: a source, amplification, and speakers.

Your source could be anything from a music streaming service played on your smartphone to a turntable you could even use a CD player if you still have one.

An amplifier takes the weak electrical signal generated by your source, and powers it up enough to drive your speakers. Its worth noting that many sources come with integrated amplifiers even your smartphone contains a small amplifier, though using a separate DAC (Digital-to-Analogue Converter) improves the sound quality dramatically.

Lastly, there are the speakers. Theres lots of choice when it comes to this component, whether youre looking for clever wireless speakers, powerful floor-standing speakers, or space-saving bookshelf speakers.

Setting your budget

Building a Hi-Fi system doesnt have to be a huge drain on your bank account; sure, you could spend thousands, even millions on an enormous state-of-the-art setup, but theres really no need.

What do I need?

If you are trying to limit the amount you spend, its a good idea to work out what kind of kit you might already have at home. As we mentioned, you could use a smartphone, laptop, or TV as your music source, which would work well with wireless speaker systems from the likes of Sonos, Bowers & Wilkins, and Harman Kardon.

Got a turntable knocking around in your attic? Check whether your record player has an integrated phono stage if it does, you could save money on buying an external amplifier. Similarly, you can save money on an amplifier by purchasing an all-in-one music streamer like the Naim Uniti Atom all you have to do is add some speakers, and youre good to go.

Only have the budget for one speaker right now? Check out models that feature 360-degree grilles and disperse audio at all angles; the Amazon Echo Studio or the Sonos One are good places to start.

Cables, stands, and other add-ons

If you do opt for a wired system, be sure to budget for cables; high quality cables can cost upwards of $40 / 40.

Similarly, you should consider whether you need to buy stands or wall-mounting kit for your speakers again, these extras can quickly add up and its easy to forget to factor them into your budget.

For your source device and amplifier, consider whether you need to buy a stand or AV rack to keep everything neat and tidy; if youre using a turntable as your source, make sure you have a sturdy, solid surface for it to sit on. You dont necessarily have to buy new furniture for this you can save money by repurposing what you already have.

Designing for your home

Theres no point in paying for some enormous floor-standing speakers if your space is small; similarly, a pair of tiddly bookshelf speakers probably wont cut it if youre building your Hi-Fi system in a big space.

Similarly, you need to think about the purpose of your Hi-Fi system. For example, if you want it to double up as a home cinema setup and are using your TV as your source device, you may want to invest in a soundbar that can be easily wall-mounted or placed on top of your TV stand.

The placement of your speakers is hugely important to the audio quality your Hi-Fi system will be able to achieve; ideally, stereo (left and right) speakers should be at least two meters apart, and tilted very slightly towards where youre going to be sitting and enjoying your music.

While space constraints may leave you without much choice, try not to place your speakers in corners or too close to walls this can cause the bass to muddy the other frequencies.

As well as saving money, buying integrated components like a turntable with a built-in phonostage or an all-in-one music streamer saves precious space when its at a premium.

Be sure to factor in any additional furniture that might take up space; stands and AV racks, for example.

Additional features to look for

These days, lots of the components that will make up your Hi-Fi system come with additional smart features like wireless connectivity, multi-room playback, and integrated voice assistants.

Lets talk about wireless speakers to start with. Once upon a time, we might have discouraged you from relying on Bluetooth or Wi-Fi to connect your audio devices, but nowadays, the difference in quality between wireless and wired connectivity will only be discernible to the most expert of ears.

Wireless speaker systems from the likes of Sonos and Bowers & Wilkins are very convenient, eschewing annoying cables and instead relying on your home Wi-Fi network to communicate with each other. They can also be grouped into different zones so that you could have different systems for specific areas of your home.

These systems dont come cheap though, and theres no harm in looking at cheaper Bluetooth speakers, too. Check out brands like Ultimate Ears; speakers like the UE Boom 3 can be paired with each other for true stereo playback, without the need for cables. Bear in mind though, these smaller models wont be as powerful as their bulkier counterparts.

Dont forget that wireless connectivity isnt just for your speakers; many source and amplification devices come with built-in Bluetooth or Wi-Fi connectivity, including turntables, music streamers, portable DACs, and CD players.

Aside from Wi-Fi and Bluetooth, other wireless connectivity methods like Google Chromecast and Apple AirPlay are worth looking out for, especially if you already have other devices that work within these brands ecosystems.

Another important consideration when it comes to choosing your source device is whether you want your Hi-Fi system to form part of your smart home. Many speakers come with built-in voice assistants like Amazons Alexa, Apples Siri, and Google Assistant, which means they can be used to control your other smart home devices as well as being able to accommodate hands-free control.

Many source devices including smartphones and smart TVs come with voice assistants built in or at least work with them, too.

Lastly, and most importantly, you should consider how you want your new Hi-Fi system to sound, and look out for specific features that will help you achieve this. For example, if youre planning to use your Hi-Fi system as a home cinema setup, you may want to look at speakers and soundbars that support immersive Dolby Atmos audio.

Also, if youre going to be streaming primarily from Tidal or Qobuz or playing your own Hi-Res Audio files be sure that any wireless speakers support Hi-Res Audio streaming over Bluetooth or Wi-Fi.
