Well yes, the two things (sound quality + price) are inseparable. If one wants one sh*t sounding smart speaker for voice comms only then a HP Mini or an Echo will suffice, and $300 is too high.Apple has "heard more interest than ever for the acoustics of a richer larger speaker."
Have they also heard more interest then ever in spending $300 for one? Because that was the problem last time, not the HomePod's sound quality or size/form factor.
Or if one has an acoustically very good larger space then something like a pair of Sonos + subwoofer properly configured and driven can do a better value job, maybe even sound better.
But if one wants good stereo sound for music in a smallish acoustically difficult space, then a pair of full size HomePods at $300 each is by far the best choice. Good value even if self-balancing competition existed, which it does not.
