If you’re a vinyl enthusiast, then you know the importance of phono preamp in your vinyl setup, which is an integral part of amplifying your audio signal so you can listen to music the right way.

Some turntables do have phono preamps built-in, but some audio aficionados prefer to buy separate ones. The equipment will provide some much-needed sound equalization, and of course, will help to boost the signal so you can connect your turntable to external speakers.

In general, most people buy solid state phono preamp to upgrade the turntable. The reason is, they are easy to use affordable. But Phono Tube amps give stereos a much pleasant, warm, and smooth sound when compared to a regular amplifier based on a transistor. This is perfect for house parties or for when you have guests over, but it’s also a great option if you want to make the most of your vinyl and listen to good music at a decent volume, without any distortion.

Fosi Audio phono preamp is probably the best tube phono preamp for a warm and rich sound and will bring your music to life. This tube-moving magnet phono amplifier can easily convert the phono signals into line-level signals with the help of low-noise integrated circuits.

I know the pain of the low-frequency noise that develops when you listen to the music. But here, this preamp has some high-quality components that can remove them and ensure clear sound quality.

It has a 3.5mm AUX input so that you can connect it to your turntable, but you can also hook it up to your PC, laptop, or PS4. You could even connect it to your phone.

It is built with quality material that can come for long life. You get three adjustable gain levels like 39, 42, 45 dB, so you can determine and set the preamp's sensitivity, and it also offers outstanding compatibility. You can also switch out the vacuum tubes if you like (the setup comes with 6J2 tubes), although they should last you a long time.

There are several other compatible tubes you can use with this preamp, though, and your sound might slightly change depending on the tube you use, in case you’re interested in experimenting.

The phono preamp is made mainly of metal with some plastic parts and is also designed with a grounding post, so no harm comes to your turntable.

This is particularly suited to Moving Magnet (MM) turntables or MM cartridges instead of MC cartridges, also make sure to check these recommended phono cartridge for your turntable.

  • Value for money

This sleek little preamp from Little Bear is very useful and comes at a pretty affordable price, with the added benefit of not taking up much space on your turntable setup. It has an aluminum body, so it’s pretty durable, and the size also makes it quite portable in case you’re taking it to a friend’s party or an event or simply moving it to another part of the house.

Now talking about the sound quality this tube preamp offers, I must say that I was surprised by the quality of sound it tends to offer. The signal-to-noise ratio exceeds 85dB and often reaches 96dB and translates the music into the most fantastic way listeners would love.

It supports a wide dynamic range and also picks up several details of sound. Overall, the output sound is rich unless you stick with the lower gain.

In fact, in terms of a combination of price and portability, this is probably the best tube phono preamp you can get on the market, and it comes in two colors: black and silver. This is for MM turntables and doesn’t support MC turntables, so check the compatibility of your turntable before you purchase this particular piece of equipment.

This is fairly easy to set up as well, and it’s pretty much plugged and play. All you have to do is insert the tubes and attach them to the power supply, and you should be playing your favorite vinyl track in a trice. The gains are also adjustable in an updated model, which is a bonus.

This is also an AUX preamp, so you can even attach it to your PC or phone. So if you’re a bit fed up with your built-in phono preamp, and your turntable has a ‘Line Out’ switch, you should give this a go.

  • It has an elegant look
  • Gain is adjustable
  • No noise issues with the equipment
  • You get a full sound
  • LEDs included

Cons

  • Nothing much

This isn’t a small-sized preamp, and it’s not particularly modern in its look, so if you’ve got a particular aesthetic eye, then maybe this isn’t for you. However, it is super-functional, and it’ll do the job that it’s supposed to very well, which is all you can ask for from a preamp.

There is a kind of noise that disrupts the sound quality in this preamp; it can be due to low-quality RCA cables and power supply. If the connection is poor or the vacuum tubes are defective, then it creates problems as well. You can fix this problem using the instructions given in the product manual.

BUYING GUIDE FOR TUBE PHONO PREAMPS


Budget

If you’re on the hunt for the best tube phono preamp, you’ve probably got an MM cartridge, and you’re limited in terms of budget (MC cartridges tend to be much pricier). Almost all the preamps on this list are priced fairly reasonably, so they should be within your budget. It’s better to go for a budget option unless you have an MC cartridge, in which case you’re looking for something more premium.

Type Of Tube 


Also, try to pick preamps that allow you to switch out tubes and are compatible with several different kinds of tubes. If you happen to be dissatisfied with the tubes that come with your preamp, you’ll always have an alternative, and you won’t have to opt for buying a whole new preamp. 

And if you’re into experimenting with your audio setup, using different tubes is a great way to do that. It always helps to have a multipurpose device as well, so try to pick preamps that have an AUX input. That way, you’ll be able to plug in other devices (computers, tablets, phones, MP3s, etc.) if you’re not a vinyl-only audiophile.

Also, a grounding wire is a good thing to look out for because otherwise, you might hear a pronounced humming, which will distract from the music or audio.

Capacitance


The capacitance refers to the measurement of signal characteristics such as resistance or load. When incorrect loads start acting as sudden equalizers or filters, they tend to produce resonant peaks. As a result, it causes excessive capacitance. This excessive capacitance can influence the sound and makes it worse. So it is crucial to check this feature. A high capacitance value is needed for your device to deliver good sound; either low or excessive capacitance will cause distorted sound.

Cartridge


The cartridge is the most important thing to consider before buying a phono preamp. This is because only when the phono preamps remains the same type to the cartridge in your turntable it will work. For example, the moving magnet (MM) cartridge of your turntable can only work with a preamp that has a MM cartridge. 


If you focus on sound quality, then proceed with one of the tube amplifiers we have suggested. But if you want more than just amplification, consider getting turntable stereo amplifiers with phono input that includes multiple channels, AM/FM radio, USB, Bluetooth, and more features.

CONCLUSION

Ultimately, it depends on what you’re going to use the preamp for and what your specific audio needs are. If you’re a newbie, stick to a simple preamp that doesn’t require too much technical know-how, and you should be in the clear.

If you’re more advanced in terms of having a strong knowledge of audio peripherals, just pick what you think will best enhance your vinyl records. Pick the best tube phono preamp for you from this list, and you should be good to go!
