A Phono Preamplifier Designed to Get the Best from Your Vinyl Turntable
In a hi-fi system, the phono preamplifier is the component that brings the "vinyl" signal to the correct level and applies the essential RIAA correction for faithful playback. This model positions itself as a complete and scalable solution: it accepts both MM cartridges (often favored for their versatility) and MC cartridges (sought after for their finesse and definition). With its aluminum front panel and design focused on reducing vibrations and interference, it aims for a stable, clean, and coherent reproduction, even in environments where electrical noise can disrupt listening.
Who Is This Phono Preamplifier For?
This preamplifier is intended for anyone wishing to improve the playback quality of a vinyl turntable connected to an amplifier, active speakers, or a system lacking a dedicated phono input. It is particularly suitable for audiophiles who switch between multiple cartridges (or multiple turntables) thanks to its separate MM and MC inputs. It is also relevant if you want to refine your sound: the ability to adjust the load for an MC cartridge, combined with a good dynamic range at the output, facilitates integration into a demanding hi-fi chain.

Questions frequently asked
Is the Thorens MM-008 compatible with an MC cartridge?
This model features an MC mode with a gain of 60 dB at 1 kHz, suitable for the low output levels of moving coil cartridges. The MC input accepts external loading plugs. Three pairs of plugs with 10 ohms, 100 ohms, and 1 kohm are provided.
Can a turntable with an MM cartridge be connected to this preamplifier?
The MM mode offers a gain of 40 dB at 1 kHz and a fixed input impedance of 47 kohms + 220 pF. The specified sensitivity is 3.29 mVrms to achieve 316 mVrms output.
How to adjust the loading of an MC cartridge?
It is possible to insert the supplied loading plugs into the left and right MC Load RCA inputs to select 10 ohms, 100 ohms, or 1 kohm.
Is the phono preamplifier quiet in terms of interference?
Its chassis is designed to minimize resonances and interference, with an aluminum front panel. The signal-to-noise ratio exceeds 86 dB in MM and 72 dB in MC.
What RIAA accuracy does this phono preamplifier offer?
The RIAA correction is specified at +/- 0.3 dB. The frequency response remains between 20 Hz and 20 kHz within +/- 0.3 dB, while the -3 dB bandwidth extends from 10 Hz to 50 kHz.
