I have been using a soundfactory tripod stand for quite a few years now, it’s a later one with three shelves and I picked up a bigger one a few years ago, quite rare to find but very good stands though I’m not keen on the supplied boards, could be better.
As @bruss says, it depends on the wall and floor. If it’s a load bearing masonry wall, then great. If it’s plasterboard then it’s complicated. A rack on a floor is probably better… unless the floor is sprung.
Designed my own which my Cabinet Maker built for me.
Solid Cherry frame, just like my Naim Fraim shelves. They match perfectly
Spiked legs that are into shoes and stand on an isolation platform suspended off steel dowels drilled into the concrete sub-floor.
Turntable platform is 20mm Quartz sitting on spikes screwed into the frame.
The two shelves are 10mm toughened glass.
My listening room is a timber cabin with a suspended wood floor, which is too susceptible to vibration for wall mounting. Hence the isolation platform😉
