Thorens MM-008 Analog to Digital Converter (ADC)
For many of us who have gotten used to the relatively superior convenience of storing, accessing and playing digital music files, it is quite a chore to play our music collection on vinyl records. It is a pain to gingerly take vinyl records out of their sleeves, place them on the turntable, clean them and then carefully place the stylus on the disc. It is also a pain to repeat the whole process every 20 to 25 minutes when the stylus reaches the end of each side of a vinyl record. I also find it annoying trying to place the stylus on exactly the right spot when I want to hear a particular track on a vinyl record and it is not the first track on the disc.
In contrast, with digital music tracks, all you need is just one or two clicks of the mouse to instantly play any track in your collection and, unlike vinyl, you can make your favourite playlists for every one of your moods and jump from any track to any other track, again, with just a click or two without even leaving your sweet spot.
To transcend the drawbacks of listening to vinyl we have the option of converting all our vinyl based music into digital files and storing them on our computers or external hard drives so that we can enjoy them with the convenience that digital playback offers. However, hitherto, we had to opt for either the very affordable USB turntables that made the process very simple but resulted in digital files that are a poor facsimile of vinyl playback in terms of sound quality or alternatively, we had to spend big bucks to acquire a high quality analog to digital converter to turn our vinyl based music into digital files that had sound quality that is acceptably close to vinyl playback.

It was therefore with great delight that, at TAVES 2013, I happened upon an Analog to Digital converter that had most of what I was looking for. It is compact, well built and at $450, reasonably priced. It did not hurt that it is made by Thorens, a highly reputed vinyl component manufacturer from Switzerland. The bonus is that this little unit doubles up as a moving magnet/moving coil phono preamplifier as well. I immediately asked Robb Niemann, the CEO of Rutherford Audio, distributor for Thorens, when he could send me one for a review. He explained that this component was not officially launched yet, but I could expect to receive a unit when it did make its debut. The wait was long, but as they say, good things come to those that wait and in mid 2014, I finally received a review unit of the Thorens MM-008 ADC. According to Robb, the Thorens ADC was extremely well received and he is selling them as fast as he can get his hands on them.
The unit arrived in a compact and very well packed carton that should shield the MM-008 from the vagaries of most of the rough handling that it could be subjected to during shipping. The unit itself has a very elegant, minimalist design that consists of a silver or black brushed aluminium façade with no controls and just one blue light at the center. The unit I received was the silver version.
The rear of the unit is also very well laid out and consists of an MM/MC selector switch and RCA sockets for MC loading, stereo MC and MM inputs from the turntable, a power switch, a power socket, a pair of RCA stereo analog outputs, a USB socket that outputs to a computer and a binding post for a tone-arm earth wire.
The box also contains three (stereo) pairs of RCA terminated loading resistors. These have values of 10 Ohms, 100 Ohms and 1,000 Ohms and will allow you to fine tune the load on the MM-008 to more closely match the specifications of your phono cartridge, if you use the moving coil variety. To determine which load is the most appropriate, you need to check the manufacturer’s specification of the MC cartridge that you use. When using a moving magnet cartridge, the MM-008 offers a fixed resistance load of 47 kOhms.
The MM-008 comes with an outboard power supply which allows you to keep the power supply unit well away from the ADC itself where it cannot adversely pollute the circuits with the noise that it emits. When you connect this power supply to a power conditioner, you should ideally plug it into a socket that is isolated from the other sockets so it does not adversely affect the components that are plugged into the same power conditioner. The MM-008 consumes just 3.5 W/ 15 mA and is designed to be left on all the time.
