Ive also heard Pioneer Elite has a new receiver coming out but its not on their site, or maybe Im just misinformed.
I don't know about the Elite line, but regular Pioneer has the '19 series of receivers waiting in the wings. Usually the Elites follow a little bit later.
Audioholics has a test review of the SC-07, a mid-range Elite model. It didn't respond well to a broadband test into a 4 Ohm load, but the report went on to say musical content into an actual speaker should be OK.
I have a 1018, their current top-of-the-line standard model. If someone wants to give me a pair of M80s, I'll be happy to report how it handles.
