LHY now has the SW-6. Despite the lower product numbering this sits between the SW-8 and SW-10 and I believe it will even be superior to the later because its not repurposing cheap commercial switch hardware - it's a custom board design.
To my knowledge the only other switch that is custom built for audiophile considerations is by Nordost and its very expensive. Even those crazy expensive Ansuz switches use commercial boards inside.
Because the SW-6 is a custom made board the clock is now located right where it needs to be rather than on a daughter board. Also one output has dedicated isolation from the other 4. It has a SPF connection as well if you want to do optical.
