There are a number of designs around for devices that will allow for self-administered ABX testing. The switching and level matching are usually fairly similar for a given sort of device under test. The controllers have more variation, with software, discrete logic and mechanical switches having been used in different designs to produce randomness in X. See for example https://sound-au.com/abx-tester.htm or https://www.head-fi.org/threads/discrete-logic-abx-switch-box.625791/
The first problem is that they aren't readily available off the shelf. If they were available then they'd be both too expensive (you want me to spend how much to 'prove' I can hear this night-and-day difference???) and not expensive enough (clearly the device isn't transparent enough, which is why I can't tell the difference). Or we'd end up in arguments about whether you could hear a difference in the sound of the switching rather than in the device, as has been documented in at least one of the papers.
