I use it for two weeks. Good quality product despite a nasty surprise after order with Thomann for the model supplied was defective (rare in SPL). Return and repayment of Thomann and purchase of another at the Universe, no problem.
The interface is very simple (although somewhat surprisingly), the sound is hardly colorful. Connected to 5 Focal Solo 6 and sub6, emerging from Apogee Ensemble, the whole is coherent and easy to use.
In this price range, it is a product without competition.
Too bad the Soviet period look is so 1960 and hit the buttons a bit plastic. The large volume knob is very nice, smooth and precise.
I use it for 4 years and this is my first model.
The analog control system 5.1 and stereo becomes a formidable simplicity, the image speaks for itself.
The Knob is a marvel of taking "fingers" and reacts to the slightest movement, the more I find the sound even better.
It can manage external sources and stereo surround.
Further provide a multicore 8-channel D-Sub to receive the output of the soundcard.
The product is cheap but the quality is Pro.
