@david_ten Hello there, I am a few days away from getting the T+A PA 3100HV. It's shipping from Germany next week. I got the APM option added. Does your unit have this? If so, I'd love to hear your experience with this. I brought the demo unit from my dealer home and auditioned it. It did not have the APM, so no tone control. However, I was stunned by how beautiful it sounded with the A3s.. Thanks..
