Is this the s660h or the s650h? the title says 660, but then it days "style: avr-s650h". they're different products, so which is it?

They may have just reused the copy in the ad from the 2020 version (AVR-S650H) in making the ad for the 660 and just changing the specs without catching the 650 in the text description.
