I’m not sure anyone who’s serious about audio quality is looking at Sonos either.
I guess it all depends on the magnitude of one’s “seriousness”
I already have a Sonos system and it sounds pretty good. Not great, not perfect, not fantastic, just pretty good.
It is used in my entertainment room in the basement. It is the surround sound system so I have the bass cube and sound bar and two Play 3 for the rear speakers.
When I kept hearing HomePods were going to compete with Sonos I was interested. I intend to add speakers to other areas of my house and maybe I should wait and see what the HomePod can do. At $350 for an all in one speaker/amp/network I wasn’t expecting glorious heavenly sound I was expecting pretty good sound. That’s ok I have a higher end stereo system for my serious listening and I know Sonos doesn’t match that system and I don’t expect HomePod will either.
Music can never be better than its source material. Play a cheap vinyl record on a high end system and you will hear each and every pop and scratch. You want to hear what your system can really do then you have to have good source music to start with. Streaming music is not great source music. It’s ok, it’s better than my cheap vinyl example but it’s only average quality. Someday that may not be true. Someday they won’t compress/clip/restrict sound file size to make it smaller so it fits on whatever media or streaming technology is used. That day isn’t today.
I can play my better source material thru my Sonos speakers. Once again, I have a better speaker/amp system in my house so I know that Sonos sounds good but not great. But they sound as good as I can afford to make them sound.
Apple has made the deliberate decision to limit what I can use as my source material. Plus there are current limitations as far as number of speakers and functions - right now there is no stereo sound and no ability
to add a bass unit to deepen that sound range. One of those 2 problems they have promised to fix, stereo, but no word at all if they intend to expand it further than that at all.
I was looking for a sound system and not a voice assistant. I don’t give a damn if I can ask Siri/Alexa/Google a question and get an answer or turn on a light using my selected sound system. Right now I don’t trust ANY of these providers to not sell whatever information they are mining. When these speaker systems are $30 or less the company isn’t making money selling that speaker to you, they are making it by selling you to another company. So my focus was on sound, expandability and how easy it was to use my current music. And that’s why I’m disappointed with HomePod.
