Thank you for the compliments, The Beta 4 column System uses one Pc5002m for the mid to high towers the other 5002 the woofer towers. The TV section which is 6x 0.2 infinitesimal Speakers and the SSW 212 use the Pc4002m amplifier systems can work independent or jointly. My pre amp is a Yamaha Cx1000. All of which has had time consuming thorough retrofitting and tuning. IMO it’s a clean sound and all complement one another. Certainly nobody gets too warm, clipping is completely out of the question.
