After having the MRX 510 for a few weeks now, I gotta say phenomenal on the sound quality. It sounds as expected from an Anthem AVR.
Ok, so now let's compared it the MRX 300 or otherwise first gen since they all sound the same anyway. Before I say anything, this is a comparison on the music side not for movies.
I think the first gen were a bit brighter while the second gen sounded more neutral. I got more ear fatigue on my paradigm speakers using the 300 compare to the 510 after listening music for over an hour. Here is where the second gen MRX receivers fell short of. The bass is much different sounding and weaker compared to the first gen. It's not bad in anyway, it's just weaker. The bass on the first gen was much more authoritative and more gut wrenching. On the 510 I couldn't get the same kind of bass power especially the lower frequencies band as good as the 300 at any given tone control and volume levels. As for clarity and mid range sound, they both sounded fantastic and nothing to complain about here.
I'm guessing for movies the 510 would be much better perhaps.
So for those that had both first gen and second gen MRX AVRs, what would your thoughts on the sound quality?
