Steve, I'm not sure I follow everything you're saying about angle errors, but there are a few installations that work well here in the SF Bay area that I have personal experience with. The Listening Room at Stanford's CCRMA is a 3rd-order periphonic facility, described here
https://ccrma.stanford.edu/room-guides/listening-room/ The others are in private homes, so I'll let the owners to chime in if they please. They're good sounding rooms, but without special acoustic treatment. (unlike my living room, which is glass on three sides). There are several accounts of Ambisonic reproduction not working well in very dead rooms, such as an anechoic chamber. Also, for 3rd order periphonic you need to place a number of speakers below the listener, which can be a challenge. The acoustically transparent floor in CCRMA's Listening Room is one solution. Eric Benjamin and I have a paper in the upcoming Linux Audio Conference on designing HOA decoders for partial coverage speaker arrays, such as domes and rings.
