Tube amplifiers are held in high regard by many audiophiles because of the euphonic distortions and flavors they add to the music. These effects are so subtle that only hi-fi enthusiasts are able to discern. If you’re wanting to get the best possible tone out of your hi-fi system, you’re going to want to find the absolute best tube amplifier (to go along with one of your outdoor stereo receivers), and this is exactly what this article will help you do, so you should definitely stick around.
What Are Tube Amplifiers
Simply put, tube amplifiers are models that utilize vacuum tubes or valves in order to amplify the electric signals that musical instruments send when plugged into them. Such electric signals are produced by pickups, in the case of guitars. Then, they make their way through the preamp and power tubes of the amplifier before eventually being released as sound through speakers.
How to Choose a Tube Amplifier
Before selecting a tube amplifier, there are a few factors that you must take into consideration if you wish to ensure the most value for your money. Let’s discuss these factors very briefly.
Tone is everything when in the market for a tube amplifier. You can’t just buy an amplifier based on the input of others, no matter how valuable the input is. Tone is completely subjective and is a matter of personal preference. What one person deems as an excellent tone might not appeal to you. It’s important that you listen to different tube amplifiers in person before formulating your opinion so that you end up with a model that you really like.
Will you be using your amplifier mainly at home, gigging bars, or large venues? Do you want an amp that breaks up at lower volumes or do you prefer high headroom? These are all questions that you need to ask yourself when trying to select a tube amp based on wattage. Keep in mind that tube amplifiers sound their best when pushed a little.
You can have an amplifier that boasts very high wattage, but if you can’t crank the volume up for whatever reason, like not wanting to disturb the neighbors, you’ll never get to witness the amp’s true potential. Per contra, if you have an amp with fairly low wattage, you’ll be able to play it at lower volumes and witness its potential because the tubes will be pushed to clipping a lot easier.
Different power tubes flaunt different sound profiles due to dissimilar characteristics. 6L6 tubes, for example, flaunt remarkable roundness and clarity, whereas EL34 tubes are known for their excellent lows and midrange. Robust tubes such as the 6550 or the KT88 are proficient when it comes to producing an ultra-clean sound that’s reinforced by low-end frequencies. If you’re into smoothness and harmonic distortion, opt for an EL84 or a 6V6 tube.
Just because an amp is expensive doesn’t necessarily mean that it’s better than lower-priced counterparts. It all boils to your personal preference in tone, once again. You can play a pretty expensive amplifier and not like its tone. Per contra, you may find a wallet-friendly amp that’s perfect for your tonal requirements. You must also keep in mind that some amplifiers are only expensive because famous musicians use them.
5 Best High-End Tube Amps in 2021
Tube amplifiers come in a variety of shapes and sizes with different specifications, which is why trying to pinpoint your ideal amp can be quite overwhelming. To simplify your selection process, we’ve managed to narrow down your options to just 5 quality amps that are sure to impress.
1. Muzishare X7 (<—- MOST POPULAR!)
The Muzishare X7 is one of the most versatile tube amplifiers available today. It can be used for a wide range of music genres, whereas other competitors are designed for certain genres only. It can be linked to a preamp signal input, and with the aid of the phono function, you can easily connect it to your phono player. Like the X5, point-to-point hand welding is used for this amp.
The X7 comes with a host of accessories that you’ll surely appreciate, from the infrared remote control and tube protective cover to the interconnect table and detailed instruction manual. Also, the device flaunts an impressive 45W output, which means that it can withstand being pushed to extremes. This, however, doesn’t mean that it’s louder than a solid-state unit of the same rating.
The amplifier uses a Z11 core toroidal power transformer, which grants it a few advantages over conventional transformers. First of all, it’s significantly lightweight, which is a result of the toroid (doughnut) shape and not cost-cutting. In addition, it’s perfect for delicate electronic systems, as it flaunts low-radiated electromagnetic fields. All in all, it’s a very well-rounded tube amplifier.
Richard said, “The amp arrived in flawless condition with the tubes properly installed, and boy does it sound fantastic. I really like this amp!”
Victor said, “While still in the break-in process, I’m very impressed with the packaging, finish, and presentation. This one is quite the looker.”
The downside to buying this amplifier is that it truly embodies the term ‘high-end’ in the sense that it’s quite expensive. It certainly delivers an excellent bang for the buck, though.
