I have been doing some research on stepping up to a prepro+multich amp separates in the future. I recall the AudioScienceReview guy (Amir) stating that manufacturers just pull the amplifiers out of a flagship receiver and sell the "amp-less receiver" as a prepro at a higher cost.\n\nBut, watching Phil Shea's response from Yamaha, he appears to paint a different picture on how their prepros are designed over the course of this video, a.k.a as a very different design from the ground up. Was the ASR guy just spouting out the wazoo on this topic? Or do some brands\/manufacturers actually just remove amp sections and rename it as "the prepro"? If so who does that? Integra? Denon? Marantz? Pioneer? Arcam? NAD? What brand of prepro was the ASR guy referring to?
