When Thorens releases a new phono preamplifier, it’s always an event. And the MM 008 ACD is quite different to earlier models. As well as being compatible with both MM and MC cartridges, the MC input is adjustable and an it has an A/D DAC, letting you convert your vinyl records into digital format using its USB output.
It also has an RCA input for moving magnet cartridges (MM) and another for moving coil cartridges (MC). The two circuits are completely separate and can be selected via a switch on the back panel. This is an attractive feature if you own two vinyl turntables or two tonearms. The MM input has a load of 47 kohms and a capacitance of 200 Pf. The MC input can accommodate jacks with the appropriate resistive loads (10, 100 and 1 Kohms), ensuring perfect compatibility with the majority of cartridges on the market.
Its USB 2 output also lets you convert your records into high quality digital format using free software such as Audacity (see link below) or a range of other computer programs, including Garabande, Cubase and ProTool. This output is fully compatible with Windows, Mac and Linux operating systems.
We strongly recommend that you make these recordings at 24b/96 Khz and in FLAC or WAV format, or even Apple Lossless. Whatever you do, just stay away from MP3 format!
This preamp has an external power supply which delivers a stable and silent 24V direct current. The casing is quite massive and the brushed aluminium front panel is quite something!
The production quality is excellent - understated and effective.
The listening experience is transparent and punchy. The noise level is very low, inaudible even. The sound quality is very clean, defined and precise and does justice to every register. Overall it is very well-balanced, which is an undeniable advantage, making it compatible with many cartridge models. Indeed, this neutrality makes it very versatile.
