As always with Magnat quality material even for the entry level Being equipped Magnat Vector Needle for 10 years for home theater use, I ordered the 301A sub box waiting to get my omega of the same brand that has to deal with an electrical overload during a thunderstorm (thankfully fuses limit the damage) and I must say I'm not disappointed, especially given its price low infra ... it does better than defend and follow up sufficiently to install a 5x100W (use only a 1/3 of its power to be in harmony with my columns). In short that's good for a brand unknown German home but worthy of the best in sound quality. Usage favored: home theater. Complete settings on the rear plus a clear instruction (which is rare these days).
