MM-only phono stages are designed to amplify the signal from MM cartridges to line level. They are typically less expensive than MC phono stages, and they can offer excellent sound quality.
When choosing an MM-only phono stage, there are a few things to keep in mind:
- Gain: Make sure that the phono stage has enough gain to boost the signal from your turntable to line level. Most MM cartridges have an output voltage of around 2.5mV, so you will need a phono stage with a gain of at least 40dB.
- Equalization: Make sure that the phono stage has the correct equalization curve for your turntable. The RIAA equalization curve is the most common equalization curve used for vinyl records, but there are a few other curves that are sometimes used.
- Inputs and outputs: Make sure that the phono stage has the correct inputs and outputs for your system. Most phono stages have RCA inputs and outputs, but some also have XLR outputs.
- Features: Some phono stages have additional features, such as built-in headphone amplifiers, subsonic filters, and multiple inputs. Consider which features are important to you.
- Price: Phono stages can range in price from a few hundred dollars to several thousand dollars. Set a budget before you start shopping.

Here are some additional tips for choosing and using an MM-only phono stage:
- Match the phono stage to your cartridge. Different cartridges have different output voltages and impedance. Make sure that the phono stage you choose is compatible with your cartridge.
- Use high-quality cables. The cables that you use to connect your turntable to your phono stage can have a significant impact on the sound quality. Use high-quality RCA cables to get the best sound possible.
- Experiment with different settings. Many phono stages have adjustable gain and equalization settings. Experiment with different settings to find the ones that sound best to you.
- Give your phono stage time to warm up. Most phono stages need a few minutes to warm up before they sound their best. Turn on your phono stage at least 15 minutes before you start listening to music.
By following these tips, you can choose and use an MM-only phono stage to get the best possible sound quality from your vinyl records.
