How to prevent visitors from touching your system

Friends to touch my audio gear, who needs friends when I have records to fondle er ah play. Aaaaaahhhhhh vinyl.

No, no, no, is that a Scratch what to do, what to do, no,no,no,no.

Records to die for, equipment to touch. 

I have a cage of barely visible chicken wire around my rack which has the same voltage as my 300B vacuum tubes, i.e. 450V. When folks touch it they get really shaken up, which triggers a trapdoor right under them, landing them on a heap of old cassette tapes in the crawl space.

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).
