While hardly perfect the RJ45 A/B switch is a good option. There are not issues with both units being controller, volume updates immediately upon next volume press, and the source stays synced when switching from one input of the RJ45 switch to tbe other. There are both RS-232 controlled versions as well as a contact closure version. With the 12v triggers on the Meridian gear, a seamless automated operation can be done using a 12v relay. In the case of a 218 there are no IR remote issues as it can be IP controlled via the App and the two controllers can operate independently.
