Ask most people what makes quality music, and inevitably they reply that it’s the speakers. I’m not sure whether that was ever true, or if the speakers were simply one of the few pieces of hardware that users could choose, but it’s definitely not the case in this age of digital music.

Speakers do matter, of course. However, thanks to printed circuits, selecting them is no longer a matter of the larger the better. Today, you can get the same sound from a eight centimeter high wireless speaker that you once needed a seventy-five centimeter wired speaker for. And, although you still can’t go astray with traditional quality brands such as Bose, other brands like Logitech’s UE (Ultimate Ears) are also worth considering.

If you use headphones or ear buds, the headphone amplifier on your music player takes the place of speakers. For example, Fiio, an up and coming Chinese maker of audio equipment makes several different amplifiers for different listening preferences to accompany its top of the line music player. The cables used to connect headphones or ear buds can also make a difference, with those made from metals like titanium being at the high end.

Then there is the digital file. A 32 bit file is going to capture more nuances than an 8 bit one, and a 192K sample rate more than a 42K one, regardless of what hardware you play them back on. Format also matters, with FLAC being preferred by many audiophiles because of its advanced capabilities.

Still another consideration is the DAC (Digital to Analog Converter), which turns the digital file into sound. Unlike with speakers, with DACs, size still matters – a music player the length of your thumb does not have room for a first-rate DAC, which currently requires a device about the size of a cell phone. Even so, modern DACs deliver quality that was once only available with several bulky boxes many times their weight.

All these considerations are often bundled for you. Download sites, for example, often offer low quality files in MP3 formats, with occasional special offers of files with a higher sampling format. Similarly, headphone amplifiers and DACs are usually not compatible with other brands, or even other formats, although headphones, ear buds, and cables generally are.

If you are ripping your own digital music or selecting a music player and its accessories, take into account where you will play music. An apartment dweller will have little use for Fiio’s A5 headphone amplifier, because they are unlikely to be playing music loud enough to appreciate its ability to keep the bass from distorting at high volumes. Instead, the less specialized A3 headphone amplifier is probably a more reasonable choice. Similarly, if you want music for riding the bus, even with noise-canceling headphone, you will probably have enough external noise that you can’t appreciate a 32bit FLAC file, and it will simply take up extra storage space.

Sorting through all these considerations can be complex. All the same, don’t just stop with the speakers or headphones when you are considering how to play your music. Today,  focusing on the speakers is only part of what you need to consider.
