The phono preamp, also known as phono stage, phono preamplifier, RIAA preamp or turntable preamp is an electronic circuit that applies the correct amplification to the signal coming from your cartridge and sends it to the input of a power amplifier or audio system. The audio signal coming from the needle on your turntable is very low and requires amplifying (up to several hundred times) to bring it up to the standard line level (also referred to as AUX) that most modern amplifiers require. It basically provides the connection between the record player and your amp, and converts phono to line level.
The audio recorded on vinyl has RIAA equalisation (a specification for the recording and playback of phonograph records, established by the Recording Industry Association of America - RIAA) applied to it, giving less emphasis on the low frequencies and more on the high frequencies. This permits narrower grooves, enabling more playing minutes on a record, resulting in less distortion and better sound quality. On playback this emphasis needs reversing, which is achieved by the phono preamp. If you plug a record player directly into the standard line input of an amplifier, you would hear a very quiet sound with no bass, about 10% of what you might expect. Back in the day, when vinyl was the standard for audio recording, the phono stage was built-in to the receivers, allowing direct connection of a turntable (marked as PHONO inputs). As new audio formats and playback devices were introduced, and the use of vinyl records declined, amplifier manufacturers removed their integrated phono stages, so most modern ones lack a phono input and need a separate phono preamp to connect your turntable. Also, many of today's entry level turntables have line level outputs, which means that they have a built-in phono preamp, but the quality of these is often very poor, so you may want to use a separate phono stage as an upgrade. Most good and audiophile turntables don't have a phono preamp included.
Depending on what type of cartridge you're using, moving magnet (MM) or moving coil (MC), you'll need a MM or MC phono stage. Moving magnet cartridges have a comparatively high output (around 5 mV on average), whereas moving coil ones have a comparatively lower output (around 0.5 mV on average), so they require a higher level of amplification to bring it up to line level before input to your main amplifier. This increases the MC phono stage costs significantly. Some phono preamps are MM or MC only, but the best ones on the market will work with either an MM or MC cartridge, with a MM/MC switch or separate inputs. Below we selected some of the best budget phono preamps that will help you get the most from your turntable rig.
The DJ PRE II, from ART Pro Audio, is an affordable, high-quality phono preamplifier with RIAA EQ, designed for home and studio use. Formerly named the "Phono MicroPRE", it acts as an interface between your record player and your audio plyback or recording system. The built-in low noise phono preamp circuitry is highly accurate and precisely conforms to the RIAA standard. On the front of this little device there is a button with which you can switch the analog input capacitance between 100pF and 200pF to optimize your phono cartridge response. There is also a switchable low cut filter that helps remove some of the rumble on the turntable, a knob that controls the gain trim, an LED that indicates signal clipping and allows you to tweak the preamp's gain for a wide range of input sources, and a power light that indicates if the unit is plugged in. On the back, you get the phono-in and line-out RCA sockets, a hardware post for grounding the ground lead of your turntable and a 9V power input. To make the DJ PRE II smaller, the power supply is integrated on the power plug of the unit (like phone chargers). There's no power switch to turn the device off, so it's constantly consuming power unless you unplug it. Housed in a robust aluminum anodized case, this compact preamp has an excellent, detailed sound and a good, stable stereo image. The ART DJ PRE II is the most common recommended budget pre-amps under $100. DJ PRE II's bigger brother, the ART USB Phono Plus preamplifier/audio interface is an affordable solution for digitizing your records, connecting your turntable to a line input or to use it as a USB audio interface for your computer.Buy it here

Emotiva's XPS-1 phono preamp is a highly flexible unit, perfect for connecting a turntable to any line stage, preamp, or other audio equipment with line-level RCA inputs. The XPS-1 takes its cues from Emotiva's precision line-level equipment, with high-quality components throughout the signal path for accurate RIAA equalization, extremely low noise for even low-output cartridges, and vanishingly low distortion. Special attention was paid to the low-noise power supplies; both the external highly regulated AC supply and the individual switching supplies within the XPS-1. The circuitry in the XPS-1 is designed to provide the optimum gain and noise performance for both Moving Magnet (MM) and Moving Coil (MC) cartridges. You can configure the load impedance on the Moving Coil input to achieve the best sound for your particular cartridge. All the controls are on the top of the all-metal case. These include a pair of switches to set the gain for either moving coil (60 dB) or moving magnet (40 dB) cartridges. There are also two rows of DIP switches for selecting the input impedance of your MC cartridge (47Ohm, 100Ohm, 470Ohm, 1kOhm). For MM the input impedance is fixed at the industry standard 47 kOhms for a moving magnet cartridge. Its unbalanced gold plated solid brass RCA inputs and outputs are on opposite sides of the case.Buy it here
Schiit's new Mani preamp gives you the flexibility you need for both moving magnet and moving coil cartridges, together with exceptionally accurate, low-noise performance for far less than you'd expect. Many low-cost phono preamps are only good for typical moving magnet (MM) cartridges. They don't have the gain needed for moving coil (MC), or the flexibility for high-output MM cartridges like Decca, or high-output MC cartridges that that might end up somewhere in the middle of the gain range. The Mani has 4 switchable gain modes, (30, 42, 47, and 59dB) so it'll sound great with any cartridge you pair it with. Cartridge impedance loading can be set to 47 Ohms for moving coil cartridges or 47,000 Ohms for moving magnet cartridges. Mani's RIAA network is implemented fully passively. What that means is there are no poles in the feedback loop, for more consistent sonic performance. Coupled with precision 2% film capacitors, 0.5% thin-film resistors, and super low-noise gain stages, Mani delivers superb accuracy and performance, even well beyond its modest price.Buy it here

The V90-LPS from Musical Fidelity is a high performance MM/MC phono stage with superb technical performance at an affordable price. The V90-LPS has extremely accurate RIAA correction and extends up to 80 kHz and beyond. Housed in a sleek, attractive case the V90-LPS balances high-end performance with incredible value and is the perfect match for a wide range of turntables. It's separate Moving Magnet (MM) and Moving Coil (MC) inputs are each tuned to offer the best possible performance from their respective cartridges and convey a startlingly realistic audio performance. What marks the V90-LPS out from more basic phono pre-amps is the quality of the components used and the circuit design. The circuitry used owes much to the expertise gained on Musical Fidelity's high-end phono stages, giving the VP90-LPS a high-end sound at a decidedly budget price. It's housed in a full metal casing with a pleasing, minimalist design. This is ideal as it protects the delicate internal electronics from both mechanical and electrical interference, reducing the potential for sonic distortion. With the power supply located outside of the main unit, there is also less chance of mains interference affecting the sensitive circuitry.Buy it here Best stereo amplifiers for your turntable on a budget
