The Best Sound Cards in 2021

Back in the 90s standalone sound cards were a must in any PC. Motherboards of the time didn’t have integrated sound cards and you had to get one separately if you wanted to listen to music, watch movies, or play games with sound. As years passed motherboards have got much better in handling sound.

Nowadays, most quality motherboards, especially high-end gaming motherboards, come with excellent sound cards. For most users, these are more than enough. But if you want the best sound card available, you have to look for standalone models.

These come with control modules to adjust sound levels for each device you’re using, with additional ports to attach various audio devices, with a plethora of options for those who want to delve into sound recording, and with perfectly clear sound deserving of audiophile headphones and speaker systems.

We scoured the internet and found nine sound cards that should satisfy even the biggest audiophiles. We have high-end choices, excellent budget options, USB cards for those who seek for external options, and a couple of excellent DACs. Check them out below.

How To Choose A Sound Card

Picking the right sound card doesn’t have to be a hassle. While there are plenty of models out there, there are a few features you should focus on. Stuff like the signal to noise ratio, sampling rate, how many sound channels different sound cards support, connection type, whether a card is internal or external. Let’s talk about these points, one by one.

What Is Signal To Noise Ratio And Why It Is Important

Signal to noise ratio (SNR) tells about the clarity of the sound coming from the sound card. It’s basically the difference between the signal power and noise power and the higher it is the clearer the sound.

This ratio is expressed in decibels. For instance, is a signal to noise ratio is 50 dB that means that the audio signal coming from the card is fifty decibels higher than the noise signal. That’s pretty bad SNR value. With SNR being 50 dB, you will clearly hear the noise at higher volume levels. In other words, the sound won’t be clear.

You should look for sound cards with at least 100 dB SNR. That’s the lower limit you should agree to when picking a sound card. And don’t forget that signal to noise ratio isn’t the only important feature to consider.

What Are Sampling Rate and Bit Rate

The sampling rate reflects how accurately a sound card can reproduce higher frequencies. You can calculate the upper limit of the accurate reproduction of a sound card by dividing its sampling rate by two.

For instance, a 96 kHz sound card can accurately reproduce frequencies up to 48 kHz. And that’s more than enough because the upper limit of human hearing is 20 kHz. So, when looking for a sound card, a sampling rate of 96 kHz (the usual rate of mid-range cards) is more than enough.

Bit rate plays a role in the quality of recorded sound. Professional recordings usually use a 24bit rate, which is more than enough when it comes to sound quality. Look for sound cards with 24bit rate or higher.

5.1 Vs. 7.1 Sound Cards

The numbers tell the whole picture. 5.1 cards support six audio channels while 7.1 cards support eight audio channels in total. 7.1 surround sound is a bit better if you have the right speaker system, but that shouldn’t guide you when looking for a sound card.

You should just look for a card that supports your speaker configuration. If you are using 5.1 surround speakers, 2.1 system, or headphones, you shouldn’t worry about getting a 7.1 sound card.

When it comes to 7.1 headsets, they will work with any sound card if they are USB-based. USB headsets have their own sound card inside them and will have eight channels no matter which sound card you’re using.

And yes, you can use 7.1 headsets with 5.1 sound cards. They will just play six channels instead of eight. Just remember that most 5.1 and 7.1 headsets offer virtual surround. They use two drivers but create virtual surround sound via software. Real 7.1 headphones often come with their own sound cards that support the true 7.1 setup.

USB Vs. PCIe Sound Cards

USB sound cards are external cards that hook to your PC via USB port. They can be placed anywhere within the limit of the cable and some have microphones allowing users to record audio directly with the sound card.

PCI and PCIe sound cards are internal cards that have to be mounted inside your PC case. They use PCI or PCIe ports on the motherboard with most modern sound cards opting for PCIe interface because PCI ports are all but dead on modern motherboards. They offer lower latency than USB cards, at least on paper, and offer better sound quality since they can use more power from the PCIe port.

Gaming Vs. Audiophile Sound Cards

Another major difference between sound cards is their main purpose. You have models designed to offer the best gaming experience and then you have audiophile sound cards. If you want the best gaming experience but still want an excellent (but not stellar) listening experience, get a high-end gaming sound card. These often have excellent music performance.

If you have serious audio equipment and want the best listening experience go with an audiophile sound card. Those are designed to offer the best possible listening performance and to work with headphones and speakers that cost thousands of dollars.

Do note that some external sound cards made for gaming support consoles as well as PC. If you’re a versatile gamer who likes consoles and PC check whether the external sound card you’re after offers console support.

Maybe It’s Better To Invest In A Pair Of Quality Headphones Than Getting A Standalone Soundcard

Finally, if you have a quality motherboard there are good chances it comes with more than a decent integrated sound card. Instead of investing money in a standalone sound card, you should get a pair of quality headphones or a nice speaker system since your integrated sound card should be more than enough for the majority of headphones and speakers available on the market.

Budget headset would work fine with almost any sound card, but if you want a high-end headset, it’s better to get a nice headphone amp and DACadset for those headphones than to invest in a sound card. A standalone sound card should only be considered if you want the ultimate experience with Hi-Fi speakers, if you need an external sound card for gaming, or if you’re into recording.

STX II i have owned, twice. Excellent sound quality, good components, official drivers are decent, unofficial unixonar even better. Now something that is not great is the mic, its actually very bad, i would rate it worse than the cheapest onboard mic input’s i tried. The volume is to low, no way around it other than to boost the hell out of it, the result is decent volume, but horrible quality, no way around it. The EVGA Nu series i wouldnt order before taking a real good look at the number of issues with this thing. Just take one look… Read more »
