What the AI looks for in Audio Component Preamplifiers
- Phono vs line preamp
- A phono preamp adds RIAA EQ and gain for turntables; a line preamp only switches and sets volume This is the most common wrong purchase in the category.
- Cartridge gain
- About 40 dB of gain for moving-magnet, about 60 dB or more for low-output moving-coil Too little gain gives quiet, noisy playback.
- Loading options
- MM standard is 47k ohm; MC benefits from selectable resistive loading Correct loading affects tonal balance with MC cartridges.
- Noise and grounding
- Needs a ground post for the turntable's ground wire Without one, turntable hum is common.
- Built-in phono check
- Skip an external phono preamp if your turntable's preamp is on or your amp has a phono input Double phono amplification causes distortion.
Brands that matter
- Schiit Audio: Quiet, value phono and line preamps.
- Pro-Ject: Wide Phono Box range from basic to fully adjustable.
- Fluance: Easy entry-level phono preamps.
- Cambridge Audio: Alva and Duo phono stages.

What to avoid

- Using a line preamp for a turntable.
- Phono preamps without a ground terminal.
Questions
My turntable has a built-in preamp; do I need one?
No, unless you want better sound; switch the built-in preamp off if you add an external one.
