Anyone go from a single HomePod to a pair?

Picked up a HomePod to use in a rental house we are staying at for a few weeks. My first impressions is that the higher frequencies are a little lacking, but mid bass and mid range are pretty good for a small speaker. What I find missing is the stereo image - I can't get over the lack of it. For those who have a pair, do they create a solid stereo image and does a pair improve any other aspects of the sound? Btw, Apple Music seems ok. I have some fairly obscure favorites and it has yet to fail to play them. Still fussing with getting Siri to to play my playlists much less Apple's.
