PS Audio PMG Signature Preamplifier is a preamp that, according to the manufacturer, provides an unprecedented level of clarity and sound control.

Trafomatic Audio Evolution Phono One is a phono corrector with a gain of 40 dB (MM), 64 dB (MC), separate inputs for MM and MC type heads, adjustable input impedance for MC pickups (10, 20, 50, 100 ohms) and an input impedance of 47 kOhm for MM type heads. For MM/MC type pickups. This model is designed using Burr-Brown OPA2134 operational amplifiers (two per channel), which provide music playback via an analog output.

The circuit uses four C3GSE triode lamps, two interstage and two output transformers, and an LL1941 step-up transformer for the MC input. The power supply is external, with a toroidal power transformer with small scattering fields and a smoothing filter based on chokes and electrolytic capacitors Mundorf MLytic HV.

The phono corrector section allows you to adjust the input capacitance for MM cartridges (100, 200, 320 and 420 pF with an impedance of 47 kOhm), fixed gain – 38 dB. Gain switching (58 or 69 dB) as well as impedance is available for MC pickups. (5, 10, 25, 100, 250, 500 Ohms, 1 kOhm). There is a switchable roar filter. In the phono corrector mode, two outputs are available – fixed and adjustable.

The Vincent PHO-500 phono corrector is designed to "apply RIAA correction to the recording and transmit the signal to the system with minimal distortion." The main "prerequisite" for low-noise operation of the device was the power supply. The Vincent PHO-500 has a separate power supply so that electromagnetic fields cannot affect the phono corrector.

The Vincent Audio PHO-300 phono corrector is capable of working with pickup heads with both a movable magnet (MM) and a movable coil (MC). The head type is switched by a button on the front panel of the component. The phono corrector has a good signal—to-noise ratio of less than 83 dB for MM heads and less than 70 dB for MS cartridges.

The phono corrector is equipped with a single input on a pair of RCA connectors and is suitable for both MM and MS cartridges. The input impedance is 47 kOhms in MM mode and 100 ohms in MC mode. The width of the Vincent PHO-200 case is only 11.5 cm.

A tube phono corrector for connecting a vinyl record player to the line input of an amplifier. It has a low noise level, suitable for MM and MS cartridges. An external power supply is used to reduce interference.

The Vitus Audio MP-P201 Mk.III phono corrector uses the same discrete amplification cascade modules that were developed for the MP-L201 model, but for this phono corrector they have been optimized to achieve much lower noise levels.

The SP-103 features a modular design that makes it easy to perform future upgrades. An external power supply is also provided, which significantly reduces the noise level in the signal circuit. For this iteration, Vitus Audio took everything they learned and developed for the MP-P201 MkII and optimized the technology to fit a smaller body.

Features of the model: external power supply, support for mono cartridges, control of load and gain settings from the front panel of the device or using an additional remote control.

The PH 150 is a design based on a lamp transformer with an external power supply SPS 150.

ModWright Instruments PH 9.0 allows you to adjust the load on the fly, the gain reaches 66 dB for the MS section and 52 dB for the MM section. The circuit design is lamp-type.

The LCR Phono preamplifier uses only passive components: inductors (L), capacitors (C) and resistors (R). Although this is a more complex method, the unique design characteristics and performance of the LCR Phono make the effort worthwhile. Only the inductors are in the signal path; the capacitors and resistors are used in parallel circuits. This means the audio signal passes through fewer components and maintains a higher level of purity.

The YBA Passion PH150 phono corrector works with MM and MC heads. The phono corrector circuit is designed in such a way that the Passion PH150 automatically understands which type of cartridge is being used and adjusts the parameters. This is the basis of the YBA philosophy: to avoid unnecessary signal paths. The power supply of the PH150 is separate from the main amplification circuit.

The YBA Genesis PH1 phono corrector works with MM/MC and MC high output cartridges. The selector knob on the front panel of the F1 has only two options (MM or MC), although it accepts MC with a high output level. The circuit is designed so that it automatically detects which type of cartridge is being used, and the appropriate settings will be adjusted if selected correctly using the toggle switch on the back panel.

The YBA Heritage PH100 allows the resistance of plug-in MS cartridges in the range from 2 to 100 ohms, the phono corrector can also function with MS pickups with a load of 47 kOhms. The accuracy of the RIAA curve is very high - within 0.3 dB over the entire frequency spectrum, distortion does not exceed 0.005%.

Three-block phono corrector-preamp Lamm LP1. Dual mono tube preamp with two separate neutral power sources equipped with full-wave vacuum rectifiers, choke filters, high-voltage vacuum lamp regulators, solid-state analog non-switchable low voltage regulators used as heater power sources. Lamp set: two-6C3P (6C3P), two-6C45P (6C45P) and (phono corrector); four-12AX3/12 BE3, two-6C19P (6C19P), two-6AK5, two-5651A (power supply).

A tube phono corrector, assembled according to the principle of double mono. RIAA correction is passive, on high–quality elements with minimal tolerances. There is no general negative feedback. The amplification stages are based on unique 417A/5842 lamps manufactured by Western Electric, which have high steepness characteristics.

The Octave Phono EQ.2 is able to meet the needs of most fans of high-quality analog sound, dissatisfied with budget phono correctors, which are integrated into amplifiers or preamps and in most cases are manufactured according to the residual principle.
