0.6in taller, and a barely over the width of 2 homepods... seems like you have a very
thin line between what is considered big and bulky. Heaven forbid you get near some "REAL" speakers. I guess those would be what, humongous? Ginormous? Colossal?
However you want to sway what I said, the fact remains, The google max will forever have more stereo separation, and proper reproduction of the channels of how tracks were recorded. All day everyday over the homepod. Because the homepod cannot distinguish left from right channel. It wouldn't matter if the Max's speakers were any closer together, or spread 4ft from each other. It will still properly play the L and R channel in accordance to how it was meant to be played back. The homepod will never in a million years be able to do this, unless Apple pushes an update to define L and R channel. And at that point, it would be confusing with the amount of drivers, positioning, etc.
And what you have mentioned are things that you consider points based on your POV of the device. Different strokes for different folks. The average customer on the other hand apparently do care. In fact that is why there is so much controversy surrounding the homepod in the first place. Because of its lack of features, sub par assistant, and many don't care for the synthetic sound algorithm that Apple uses for auto-eq.
I like technology in general. I love audio as well, hence me being around in plenty of discussions surrounding the topic, as well as my profile pic. I personally don't own a Google home max, nor plan on buying one. I stick to a quality pair of speakers, which can be hooked up to a smart assistant, and voila. Best of both worlds. Not sure why you are questioning why I am here. Unless I missed the rules/requirements to view/post on this site, I am unsure what the relevance of my answer would be for you?
