Audio stuff I've lost in my own home...

I have lost several cartridges among many other things. One right off a shelf; no , no one else took it unless it was the little people. I can't find some parts I ordered for a tone arm right now; the anti skate outrigger for my Grace 707 has been missing for a couple of years. I have a box of parts for my SME arms that is here somewhere [maybe]. I haven't seen my good multimeter in a few years either. All told, you aren't doing badly.

If security camera will not help, than you should contact ghost hunters to install their equipment in your home.

I once misplaced a pair of Apogee Scintillas.

Finally found them when we moved.

You all are just trying to make an ADD wetland scientist and music lover feel good. 'Course I never lost a pair of speakers...yet. Pretty much everything else.

I found a pair of Grafyx SP-6 speakers packed away in my basement a while back. I had wondered for years what had happened to them.
