However, the cable fit very well, and sit, as always with the optical connectors, very firm. Very firm is also the rotary switch above. You have him only squeeze to release the fuse (see picture in the article description), only then he can be turned. He snapped very well at the individual inputs, and it appears to the currently active input a bad to be recognized red dot. Slipping is fairly well prevented by six rubber feet on the ground.
Dropouts in the sound I could find at any of the inputs.
To me, the switch bit large, but very robust for this price. Unique buy recommendation.
