I enjoyed your recent review of the MRX700. I noticed this unit was placed in the recommended purchases for av receivers under 2000$. How would you rate this unit vs higher priced units? Notably, pioneer sc-37, onkyo 5008 and denon 4311, arcam avr600. My main question concerns 2 ch stereo in these receivers. Thanks for any input.

From reading the review, it appears this is a powerhouse of clean sound. I think you mention it was only bested by separates you have tested in room filling clean sound. If you look at the Lab tests watts/% distortion it seems rather low? The Pioneer elite SC-37 seems to have way more clean power than the onkyo? Am I reading this wrong? The Integra also seems to have a cleaner amplifier section that the big onkyo.

According to these lab results this flagship puts out the same watts per channel into 5 channels at 8 ohms as the TX-NR609 (cost $600 vs. $2600) also reviewed and measured in these pages.
