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.

What is total power output

-Number of Power Amps 5 -Power Output (8 ohm, 20 Hz - 20 kHz, 0.08% 2ch Drive) 75W -Power Output (6 ohm, 1 kHz, 0.7% 2ch Drive) 100W -Power Output (6 ohm, 1 kHz, 10% 1ch Drive) 150W

Can I use 8k inputs for non-8k or even 4k devices?

Yes. The spec is just the maximum allowed at the input

Does it fit Bose Acoustimass 15?

Thanks for your question. AVR-S660H is compatible with Bose Acoustimass 15. World Wide Stereo – since 1979 – and a proud authorized Denon dealer.
