Stereo Amps – FAQ & Buyer’s Guide!

Written by Owen Smith

Stereo amps are amps that deliver the sounds to two or more speakers, sending different sounds to different speakers based on the music source. True stereophonic sound is when the music was captured using different microphones, and the music is then channeled to different speakers, where one speaker will deliver the sounds from one microphone, and the other speaker will deliver the second source of sound, this provides a ”real life” perception of the sound as if it were live.

A stereo amp is an amp that can split sound into two or more speakers, and the only difference between a stereo amp and a regular amp is the additional hardware or circuitry used to create Stereophonics. The amp itself performs the same duty that any amp does, it takes the weaker signal and amplifies it for louder speaker performance.

Stereophonic amps are always DC powered, so if you have an AC outlet, the amp will convert that first into DC.
Here are some tips on buying an amp.

There are three types of amps on the market; these include a tube, solid-state and digital. Tube amps are slowly dying out, where the old breed of musicians still stick to the “better and deeper” sounds of a tube, which is a load of hogwash since a tube is an electronic device that converts waveforms just as a solid state does. All you need is the right quality of solid state transistors, and you get much better performance, longer lasting, with more versatility than a tube. In fact, comparing a tube to a solid state is like comparing a Model A Ford to a Porsche Cayenne. The difference is that the tubes come with a Porsche price and are harder to find spare parts. On the flip side, the hybrids contend to provide the best performance from both worlds. Well, let me ask you this, of tubes are so god darned magnificent, why are we all clambering to buy the latest LED TV and not some oldie tube model?

The next issue to look at is power, and yes power is important here. Amps use watts, as do speakers, and you cannot hear any music without speakers. As such, the amps and speakers have to match or you either get a weak amplification system for strong speakers or get an overpowered amp system blowing away the speaker electronics.

Amps should be equal to but no more than double the wattage of the speakers.

In terms of power size, here too you want to go for lower than higher.


ider that a standard auditorium or club hall system uses 100-250 watts, you don’t need to blast the walls of your dorm or house with so much power. The average home amp system should be no more than 15 watts, and a 3-watt amp is more than enough for a bedroom practice system. 15 watts is great for garages and small outdoor jams. 25 to 30 watts is good for a small gig, and anything above 30 is going into large live performance application.

If you want to create a buzz, turn the gain all the way down and up the volume, and if you want the crunch, then is to dial a clean setting and then push the volume all the way up. Take heed that you need an amp that is equal to the speaker or double, and this means that speakers that are too weak (less than double the amp wattage) will blow, while speakers that are too powerful for the amp will just not perform.

Another issue with matching amps with speakers, especially for a stereo amp system, is making sure you have speakers with good cabinets and are high quality. Cheapo speakers will distort your sounds, and buying cheapo speakers is like making an F35 out of cardboard and duct tape, it might look like an F35, but it won’t fly.


ider getting a multi-channel amp, and make sure there are EQ’s for each channel.

Only buy an amp with a headphone jack for silent practice, and always try out the amp on your guitar before buying it. The only way you can successfully know if an amp suits you is by using your own instrument, whose sound you know perfectly well.

There is one more consideration to take into account; don’t buy an amp because everyone else has one like it, buy an amp because you like it and your instruments like it.

Now let’s take a look at the 5 best stereo amp models on the market today.
