... Faced a problem: The channel in the LARS & VAENSOON LV-2008 music column burned down. I contacted the A-2 Sphere Service, The guys were responsive, consulted, explained, and told everything how best to make repairs. The amplifier was replaced in a short time, and a guarantee was given. After the repair, the column works better (than it originally worked), I AM SATISFIED WITH THE SERVICE AND THE REPAIR DONE!! If there are problems with electronics, I will turn to you. thank you very much. I wish you success and prosperity. I recommend the service and the Guys!).
