How to prevent visitors from touching your system

The worst are children - tell them not to do something and that is exactly what they will do.

I had a friend over who was one of those 'my kid can do no harm' types and they walked into the room where I keep my main system.  I instantly told him to keep the children out of the room and he said they wouldn't do any harm and if they did he would pay for it.

I told my other friend who was there that he was a witness that friend 1 had accepted all liability for the kids. Friend 1 asked how they could break things - I told him that the delicate phono cartridge they were heading for would leave him out of pocket around $5K....and he immediately grabbed the children and took them outside. 

I have never understood how parents equate saying that the kid who destroyed something was young and not responsible also means that they don't have to pay for their child's damage.

All systems in our house include Bluesound Nodes. We have only a few visitors so it’s not much trouble to introduce them to BluOS and Qobuz so they can choose their favorite music in whatever part of the house they happen to be in. It’s been a real pleasure to see them enjoying themselves with it.  We don’t have a dedicated listening room - we’re immersed in music all over the house, inside and out (closest neighbor is almost a mile away).

Velvet ropes. And a sacred/holy Persian rug on the floor that nobody is allowed to step on. Except you (after you bow deeply.) Have an airhorn standing by in case you see someone trying to blaspheme your system.

When expecting guests, I take that day's poop that I've picked up after walking my delightful Mitsy and instead of dropping it in the trash can, i artfully place it on top of the turntable dust cover.
