KEF LS50 Meta Amp Pairing: 9 Great Amps Compared

The power of KEF speakers is truly extraordinary in the world of speakers. But The KEF LS50 Meta speakers, need amplifiers because they’re a little less sensitive.

Now, this makes you wonder- What are the best amps for KEF LS50 Meta Amp Pairing

There are 4 things to know before choosing the right amplifier for your KEF LS50 Meta. You need to consider impedance, THD+N, power, and sensitivity. Match the Impedance level to the amplifier’s power output, which is typically 4,6 or 8ohms. Then match the wattage of the speaker and the amplifiers. 

There’s more to understand about their compatibility. I’ll explain how each factor determines compatibility in this article. There are also suggestions for the best amplifiers for KEF LS50 Meta at the end.

Without further ado, let’s proceed.

Factors That Determine KEF LS50 Amp Pairing Compatibility

KEF being in business for 6 decades tells a lot about how good their speakers are.

What factors determine the compatibility between KFL LS50 Meta and Amp?

For that, you need to look into 4 things to figure out the compatibility- 


The electrical resistance of your components is quantified by impedance. It’s expressed frequently with the symbol of Ω—as in 8Ω. 

And impedance is measured in ohms. This is a factor in figuring out how well your speakers and amp work together. 

Speaker ratings commonly range from 4 to 8 ohms. The typical operating range for amplifiers is, let’s say, 4 to 16 ohms. Check whether your specifications match or not. You should be able to connect a speaker with an impedance of between 4 and 16 ohms.

In general, it’s okay to connect higher impedance speakers to an amplifier

However, you shouldn’t connect low impedance speakers—say, let’s 4 ohms—to an amplifier that has a minimum 8-ohm restriction. 

Many speakers and amp manufacturers are migrating over to using “compatible with” ohm ratings. Which makes things a lot easier and eliminates some arithmetic work and guesswork.


Total Harmonic Distortion + Noise is a measurement of amplifier effects on the output of the sound. Generally speaking, more distortion results in more sonic coloration. 

The output of the amplifier will sound more like the original recording when THD + N is lower. Speakers will, of course, have the most impact on the sound, so pick those that are suitable for your listening style. The lower the THD+N, the better the amplifier.


A common misconception is, that a larger volume equals more watts. But Watt is how power is measured. Watts is more about the amount of power that a speaker can withstand. And the amount of power that an amplifier is producing. 

Continuous Power is also known as Continuous Power Output or Continuous RMS Power. And Dynamic Power, sometimes called Peak Power, is frequently used in the specifications of amplifiers. In this article, we’ll discuss both continuous and dynamic power.

Continuous Power is the spec that tells us how an amplifier improves sound. Say the amp states, “50 watts Continuous Power into 8 ohms.” The amp will provide 50 watts of continuous power into an 8-ohm speaker. 

We’re talking about power peaks during a dynamic song or soundtrack. “Dynamic power,” is a measurement of an amp’s maximum power output when pushed beyond its limit.


Sensitivity is essentially a measurement of the decibel volume of a speaker. When powered by one watt, it measures distances from one meter away.

You read that right, just one-watt power.

What makes sensitivity important? It has a direct bearing on how loud a speaker becomes. A speaker with a lower sensitivity(85db) sounds quieter than a speaker with greater sensitivity (88db).

Even in the same room and setup when distance and power are equal. Although sensitivity doesn’t determine if a speaker is good or bad. A higher sensitivity speaker may prevent you from purchasing a larger amplifier to achieve your preference.

How To Pair Amp with LS50 Meta

Here’s how to pair an amp with your LS50 Meta-

  • Get an amp with 50% more power than your LS50 Meta.
  • Match the Ohms of amps with the LS50 Meta.
  • Put channel 1 into output 1 socket and channel into output 2 socket.

Frequently Asked Questions (FAQs)

Is KEF LS50 Meta Active?

Yes, the KEF LS50 Meta is an active model. The KEF LS50 classic speaker has been available in a number of iterations for many years. The passive version and the digital active integrated version are the only two, though. The most recent model of the passive variant among them is the LS50 Meta.

How Loud Is KEF LS50 Meta?

Regarding listening volumes, 86 dB is a loud volume. Yes, that’s a loud level, but as in power amplifiers, that 86db is average. It means that some sounds will be louder and that it is possible to briefly push speakers into distortion. It is perfect for 5 sq. m. rooms for an immersive sound system.

Is KEF LS50 Meta Wireless?

KEF LS50 Meta is not wireless. When KEF unveiled the LSX speaker system, it did away with the physical inter-speaker cable in favor of a wireless connection. It can play files (up to 24-bit/192kHz) at a maximum 24-bit/48kHz resolution. The LSX is simply a smaller, wireless version of the LS50 Meta.


It wasn’t hard to understand KEF LS50 Meta Amp Pairing compatibility now, was it? And there are a lot of amps compatible with KEF LS50 Meta as I talked about in this article.
