Cartridge Upgrade vs Phono Preamp Upgrade: Which Comes First?

The signal chain from groove to speaker

The turntable signal path starts at the stylus riding the groove. The cartridge converts mechanical movement into a tiny electrical signal. That signal travels through the tonearm wires to a phono preamp, which amplifies it to line level and applies the RIAA equalization curve. Without adequate amplification, the signal is too weak for a normal amplifier input. The phono preamp also sets loading and gain to match the cartridge type.

Because both components sit at the very beginning of the chain, their quality affects everything downstream. A weak cartridge can mask detail, while a noisy phono preamp can add hiss or hum that no other component can remove. Understanding which part is limiting your sound is the key to a successful upgrade.

What a cartridge upgrade changes

The cartridge is the first transducer in the chain. Its stylus shape, cantilever, suspension, and generating system determine how accurately it traces the groove. A better cartridge can track high frequencies more precisely, reduce distortion on loud passages, and extract more low-level detail from the record. Upgrading from a conical stylus to an elliptical or advanced line contact shape can reveal inner groove detail you did not know was there. For a deeper look, see our comparison of stylus shapes.

Cartridges come in two main families: moving magnet and moving coil. Moving coil designs typically have a lower output and require a phono preamp with adequate gain, while moving magnet cartridges are easier to match. Your choice of cartridge also affects the phono preamp you will need, so upgrading one often influences the other. Learn more about the differences between moving magnet and moving coil cartridges.

What a phono preamp upgrade changes

The phono preamp is responsible for amplifying the cartridge's tiny signal to line level and for applying the inverse RIAA curve. It also provides the correct input impedance and capacitance for the cartridge. A poor phono preamp can add audible noise, hum, or roll off the treble. An upgrade can lower the noise floor, improve channel separation, and deliver a cleaner, more dynamic presentation.

Many turntables include a built-in phono preamp, which is often a simple circuit designed for convenience rather than high fidelity. Replacing it with a dedicated external unit can be a major step forward. However, if your cartridge is also basic, the external preamp only amplifies the shortcomings of the cartridge. Understanding gain and matching is important before you invest.

Finding the weakest link in your system

The best upgrade is the one that addresses the weakest link. On entry-level turntables, the cartridge is usually the weakest link because it uses a basic conical stylus and a simple generating system. At this level, a cartridge upgrade often yields a more noticeable change than upgrading the phono preamp, because the phono preamp, even a simple one, can still pass the signal from a better cartridge with less coloration.

On mid-priced turntables that already have a decent cartridge, the phono preamp might be the limiting factor. If you hear a persistent hum, a high noise floor, or you have to turn the volume up too high, the built-in phono stage is likely the culprit. An external phono preamp that matches your cartridge type can clean up the signal.

If you are using a moving coil cartridge, the phono preamp must have appropriate gain and loading. A low-output MC cartridge without a suitable preamp will sound thin and lifeless. In that case, the phono preamp upgrade is essential before you even consider a better cartridge. See our notes on cartridge output and phono cartridge loading for more.

Maintenance and setup before spending on upgrades

Before you invest in any upgrade, make sure your current system is in good working order. The Library of Congress recommends washing and thoroughly drying hands before handling records, keeping playback equipment clean and well maintained, and storing discs by the edge. A dirty stylus or worn record can cause distortion that you might incorrectly blame on the cartridge.

Clean the stylus with a soft brush, align the cartridge properly, and set the tracking force within the recommended range. These setup steps are cheap and can dramatically improve sound. If you are still unhappy after proper maintenance, then consider a hardware upgrade.

A decision path for your budget and goals

For starter turntables, plan to upgrade the cartridge first. Many of these models come with a basic cartridge that limits detail retrieval. Swapping to a quality moving magnet with an elliptical stylus is a straightforward change that gives you a substantial improvement. If you prefer a complete solution, explore our best turntables under 300 guide.

For mid-priced turntables, evaluate the phono stage. If it is built in and you have a decent cartridge, try an external phono preamp. That upgrade will often yield a clearer, quieter background and better dynamics. You can find capable models in the best turntables under 400 range if you decide to replace the whole turntable instead.

If you are building a high-end system, think about both components together. A premium cartridge requires a phono preamp that can match its output and loading. Spend on a phono preamp that gives you flexibility, so you can later move to a moving coil cartridge. The best turntables under 600 list includes turntables that often pair well with high-end cartridges.

Ultimately, the order depends on your current weakest point. Listen for signs: distortion on loud passages, sibilance, or dullness point to the cartridge. Hiss, hum, or lack of gain point to the phono preamp. Address the dominant problem first, and you will get the most improvement for your effort.

What to pick for your use

Questions

Should I upgrade the cartridge or phono preamp first on a budget turntable?

On a budget turntable, the cartridge is typically the weakest link. A better cartridge with an elliptical stylus gives a more noticeable improvement than a phono preamp upgrade alone.

How do I know if my phono preamp is the problem?

If you hear persistent hum, hiss, or experience low volume even with the volume turned up, the phono preamp is likely the issue. Also, if your cartridge is moving coil and you are using a moving magnet phono stage, you will lack gain and proper loading.

Can I upgrade both at the same time?

Yes, but it is not necessary. Upgrade one at a time to hear the difference each makes. That also lets you decide if further upgrades are needed.

Does the phono preamp affect the cartridge's sound?

Yes. The phono preamp must match the cartridge's output and impedance. For moving coil cartridges, correct loading is crucial. A mismatch can dull the highs or cause an emphasized midrange.

Should I buy a turntable with a built-in phono preamp if I plan to upgrade later?

A built-in preamp is convenient, but it is often not as good as a separate unit. If you plan to upgrade, look for a turntable with a switchable phono stage or plan to bypass it.
