Infinity has been one of my fav speaker companies from as far back as I can remember. I have owned a bunch of Infinity speakers over the years including some IRS Beta. Sadly I got rid of those and all the rest I have owned. The current ones I own are some Quantum line source.

I have owned some Kappa 8.1

and some RS 6000
I Had some picture of the IRS Beta but sadly those got lost in a move (pre digital) Love vintage Infinity speakers, you get so much for your money.
Anyone else care to share your vintage infinity or just plain old infinity set ups?
