I think the next change to my hi-fi will be to get a new stand. Two reasons - firstly I need another shelf (6 rather than 5), and second more importantly, I am sick and tired of struggling to get around the back of my kit to change cables or install new items. So how best to achieve the second aim:
I've been wondering about mounting the stand on a Lazy Susan bearing. There are a lot of options for bearings, and the loads some will take seem to be appropriate, and I've even wondered about using a concentric pair. One of the advantages of the Lazy Susan option is that I think it would be fairly easy to have some sort of lock mechanism, that adds rigidity when not rotating.
However, more recently I've notices a number of hi-fi rack suppliers offer castors as an option, and I notice that FrostEOne's Stereo Stand plans include castors. The more I think about it, the more practical castors seem to be.
So the big question has to be: Does mounting the hi-fi on castors compromise the sound, and if so by how much? If not a lot, I think I'd prefer the practicality over the absolute sound.
Conversely could castors actually decouple the stand from the floor and improve sound?
Lastly a 6 shelf stand is quite tall - will it become unwieldy on castors?
