What I’m suggesting is that I’ve not read a Naim manual or other technical source that can can properly explain what you need to do if you cannot accommodate a rack and need to place components vertically. A lot of Naim manuals clearly show stacked components though . Perhaps their art department should start putting all their diagram of components on stands!
Jokes aside, are you able to suggest what one should do if your only viable option is to stack but your cabinet doesn’t have shelves? What is it you’re trying to achieve? Isolation, shielding, coupling or tuning? That isn’t a faff. That’s trying to understand the problem so you know exactly how to solve it.
Regards to my speaker choice there really isn’t an issue, not to me anyway. I was merely highlighting the many compromises that people have. I’d wager most people don’t give their speakers the correct amount of rear space or have them equidistant from side walls, away from hard/glass surfaces etc. In fact, looking at the system thread it’s possible to see the myriad compromises people make accommodating their hifi.
Should they worry? I don’t think so as that’s really not the point imho as it’s all about enjoyment of music.
For info as a dynamicist I deal with vibration, be it sinusoidal, random, shock or acoustic. My job is to understand the source and how to manage it.
