Phono Preamp Guide 2026 | Do You Need One? From $39

Not sure which setup is right for you?

Phono preamps confuse a lot of beginners. Do you need one? Maybe. Maybe not. This guide explains what they do, when they matter, and how to tell if your setup needs one.

What a Phono Preamp Does

The signal from a turntable cartridge is tiny and frequency-adjusted. Records are cut with reduced bass and boosted treble (called RIAA equalization) to fit more music into grooves. A phono preamp does two things:

1. Amplifies the weak signal to line level 2. Applies reverse RIAA equalization to restore the original sound

Without one, your turntable's output is barely audible and sounds thin and harsh. Something in your chain needs to handle this.

Built-In Preamps: The Common Solution

Many modern turntables include phono preamps. Look for a switch labeled "phono/line" on the back. Set to "line" when connecting to powered speakers or a regular amplifier input.

The Audio-Technica AT-LP60X, AT-LP120X, Sony PS-LX310BT, and most budget-to-mid-range turntables have built-in preamps. If yours does, you may never need an external one.

Amplifiers and Receivers with Phono Inputs

Many stereo amplifiers and receivers include phono preamps. Look for an input labeled "phono" rather than "aux" or "line." If your amp or receiver has one, use it — the built-in phono stage in a decent receiver often outperforms a turntable's internal preamp.

If you're using your receiver's phono input, switch the turntable to "phono" output (if it has a switch) to bypass the internal preamp.

A lot of people in the US already have a receiver from their home theater setup. Check the back — you might already have what you need.

When External Preamps Matter

For beginners with turntables that have built-in preamps: skip the external preamp. Spend that money on better speakers instead.

External preamps become worthwhile when:

- Your turntable lacks a built-in preamp (most Regas, many Pro-Jects) - Your amplifier lacks a phono input - You want to upgrade sound quality beyond built-in options - You're using a moving coil cartridge (needs different amplification)

Budget External Preamps

If you need one, these are the US go-tos:

Art DJ Pre II (~$39): Surprisingly capable for the price. Proper RIAA equalization on a budget. A fixture in r/vinyl and r/BudgetAudiophile recommendations. Widely available from Amazon and B&H Photo.

Schiit Mani 2 (~$149): Made in California, ships direct. Four gain settings handle both MM and MC cartridges. The Schiit stack (Mani + Modi + Magni) is a popular US audiophile starter setup. Popular on Head-Fi and the Steve Hoffman Forums.

Cambridge Audio Alva Solo (~$99): Cleaner sound, lower noise floor, solid build. Good mid-range option available from Crutchfield and Amazon.

Pro-Ject Phono Box S2 (~$150): Reliable option from a respected turntable maker. Available from most US hi-fi retailers.

How to Connect

Turntable → Phono Preamp → Amplifier/Powered Speakers

Use standard RCA cables. Red to red, white to white. Connect the ground wire from turntable to preamp (the small screw terminal) to prevent hum.

If your turntable has a phono/line switch, set it to "phono" when using an external preamp.

Common Mistakes

Using two phono preamps: If your turntable is set to "line" output AND you connect to an amp's phono input, you're applying RIAA equalization twice. The sound is wrong — boomy bass, shrill treble. Pick one or the other.

Forgetting the ground wire: Causes a loud hum or buzz. Always connect the ground.

Expecting miracles: A $50 preamp won't transform your system. Differences between preamps are subtle compared to speakers or cartridges. Focus there first.

The Honest Assessment

Most beginners never need an external phono preamp. Built-in options handle the job fine. If you own a Rega or similar turntable without a built-in preamp, the Art DJ Pre II at $39 gets the job done, and the Schiit Mani 2 at $149 is a serious upgrade.

Upgrade the preamp after upgrading speakers and cartridge. It's low on the priority list for improving sound. Our beginners guide covers the full setup picture if you're just getting started. Need help figuring out what goes where? Our setup guide walks through the whole process.
