How high-end is the RC-70? I've read all the various AVS threads and reviews but I just assumed it was just good value. There doesn't seem to be a tier system posted anywhere in the Speakers forum so I don't know where entry-level, mid-level, high-end, etc. fall within what price ranges.
Almost 20 years ago my dad spent 5x more on HT than I did just now (the VSX-D1S he gave me has more continuous wattage than my VSX-53), so I assumed spending 2k dollars on a speaker and receiver that were 50% off wasn't a big deal, XD.
To answer your question: Yes, I used MCACC to configure everything and I properly followed the receiver manual with regards to configuration. I used MCACC before the 100 hour recommend break-in period. Could I have potentially damaged the speakers? That's what the speaker manual suggests.
It could could also be that my room has too many hard surfaces, I'm gonna bring in a large fluffy rug to test that theory. So far, I think the main culprit is a lack of a centre speaker due to the little experiment I just did with my PC speakers.
I can assemble and repair computers but audio equipment confuses me...
