How to prevent visitors from touching your system

I believe part of the enjoyment is liking your equipment every time you look at it then use it.

My audiophile friends know what they are looking at, might touch something to sense it's weight/quality, never a problem.

My TT, 3 tonearms, 3 different cartridges mounted (MC; MM; Mono) I show or have shown them each tonearm's features, my method of very lightly removing paper dust, my center weight. then they can put or flip an LP. IOW, they know what they are doing, but need to understand the unfamiliar.

Non-audiophile friends: the 3 arm TT is the jewel, I walk up with them, they say "why three?", I give a simple answer, they don't touch anything.

btw, another reason to have a dust cover for your TT.

Kids: if they get close, a short 'very important to me, please don't touch, or, if older and interested, a quickie this does that.

The last intruder was served in a soup...😁

And anyway nobody want to try my old vintage tools on their head....Especially my modified Headphone AKG K340...😁

And i dont need an opinion about it...They are top of the chain and i know why.....

Alas i am old (72) fool and retired and almost all my friends were all around 18 and 40 years old...With change in life circonstances we lost touch, save by mail...

Most of them were anything save audiophiles..

The musicians i had known dont bothered themselves with audiophile sound or acoustic dedicated room, except before a concert where they think for themselves the hall is such and such etc ... 😁😊

Musicians generally dont study acoustic they study their partitions ...

Music or any qualities perceived from one or many " sound sources" in a soundfield cannot be understood by physical acoustic, even not by psycho-acoustic.. How do we explain to someone that a fruit (sound source) is ripe  with ONLY acoustic science as information ?  Usually we decide  by a perceived quality of the sound source felt first through tapping the skin of the fruit  and after the necessary experienced learning  analysis of the different  quality modalities of sound coming with this sound sources put first  in vibrating mode and expressing its body...

Ok i diverge from the question (alzheimer wandering of thought ? ) ... The only person i want to give a  try  with my audio system would be an acoustician to impress him 😁...Because i need to be alone anyway  perceiving music...

But  my most glorious and precious  musical pleasurable moments were with a more intimate friend when decades ago we compared together different pianists interpreting the same pieces together for some 5 years in once a week encounter... It is the reason why i evaluate pianists with few bar listening...

Ectasy can be partake with intimate friends...Alas! i did no more encounter with friends...They are too old or too young and busy now...

My wife never like music and love silence and anyway need hearing aids..😁

And anybody who see my low cost dedicated acoustic room wanted to put me in an asylum... They changed😁 idea in all case  only after listening the soundfield...

Now with headphone is is no more convenient to listen with someone and anyway, even if less crazy, my system did not appear in a very orthodox way to humble average mortals..

Acoustic did not matter anymore, till the time you put it under control... Before it is a very destructive power...It is like a woman... ( i joke here)

In early 2021 I took delivery of a pair of Fyne Audio F502SPs. I set them up wearing gloves and no human hands had touched them for over a year until one night in the dark I walked into one and had to grab it to stop it from falling. Not touched again by a human hand until a few months ago when someone was admiring the wood finish and rubbed his hand all over the top and side of one. I really could not say anything without looking like a nut job, so I cringed and wiped them down when he left.

@mahgister So happy you are back. I appreciate you.  

Only trouble I have had is people thinking the premium-finish floorstander nearest the entry door is a bar table for their drinks. The solution was directing traffic quickly away from the audio equipment wall. Visitors tend to be intimidated or incurious about industrial-looking electronic components. Turntable interests some folks, but it sits nearly 6' high, out of their reach. Of course, no cats or toddlers allowed.
