Anyone has tried any of the available OEM integrator - digital amplifier with DSP on their ride? Would appreciate if you could give your feedback. Came across the followings and interested to hear some of their field report. - Audison Prima AP4.9 bit (http://www.audison.eu/index.php?page=product&id=52) - Match PP 82DSP (http://www.audiotec-fischer.de/lng/en/pp-82dsp.html) - Mosconi Gladen D2 100.4 DSP (http://mosconi-system.it/product/gladen-d2-100-4-dsp/)
