Hi @dj7675.
Welcome to the Sonos community and thanks for reaching out to us. I understand your point about trueplay with the Sonos Amp. I would like to help out a bit.
I agree with @Airgetlam. Trueplay is only available for the Sonos Amp for 2 reasons, Either the Sonance Architectural speakers are the speaker used on the Sonos Amp or the Sonos Amp is used as surround audio for a Home theater set up. Currently, that’s the only supported mode for the Sonos Amp to apply trueplay. We can always send this to our engineering team to take a look into as we value all feature requests and feedback.
Please let us know if you still have further questions or concerns. We are always here to help.
Thanks,
