Could we get a group of all IRS Beta owners?

That's going to be a small group. Lots of those have been scrapped for parts. 

regretfully and regretfully.  But that is why I think it would work.  Those of us that still have them love them and want to keep them forever!

I’m still using my IRS Beta system and have no plans to replace it any time soon. It’s a fantastic system.

Still running a set of IRS Betas. I can agree with a statement made in another thread that they keep getting better as your front end gets better. The mid/hi panels sound sublime with Mac tube amps and a tube pre. I'd love to find a way to upgrade the servo box to XLR if anyone has experience there. Running the bass towers with a Classe CA-400. Simplified from Bryston 7B monos with no sacrifice in performance. A Legacy I-V2 also worked very well.

@stephens770 I have seen a modified SC unit to use XLR.  Pretty expensive proposition though.  Contact Hartmut at Bayer Soundworks in Germany.

He also has a modern take on the crossovers.

I still run the bass with Threshold 12e but the mid/high are now powered by Manley Snappers after i lost the VTL/Manley Ref 100/200.

Funny, I have a spare never used VTL/Manley Ref 100/200 but could not find another one to complete a set.  Very expensive paperweight.
