I have and SC-25 and I'm considering getting a Marantz SR7007 for the ability to run separate crossover frequencies for the sub versus the mains. Anyone have an opinion regarding sound quality of the SC-25 versus the SR7007?
The major difference is likely MCACC vs. Audyssey. If you have "fine-tuned" your Pioneer be aware that without the (expensive) Pro option Audyssey is much less flexible. However, Audyssey offers many more filters so out of the box should do a better job at compensating for the room etc.
Flip a coin.
