Who actually heard the Infinity IRS?

I've been looking at the very high value Arion speaker and it's called to mind a vintage speaker, the Infinity IRS.  They are not the same speakers, but honestly I never actually got to even see an Infinity IRS in real life, let alone hear one.

I'm wondering if anyone has or even owns a quad (pair would be wrong) of them could talk about the sound quality and compare to anything today.

I was out in Denver about a week early for RMAF 2019 hanging out with my son.

Drove over to PS Audio specifically to listen to the IRS V.  They were very busy getting ready for the show and I had no appointment, but Paul was gracious and let me in to hear the IRS.  One of the sales people demo'd the system for me and then handed me the iPad and left the room.  Quite a bit of fun...playing what they called reference recordings of all types streaming from a hard drive.  Probably there about two hours, I suspect they forgot about me. 

They throw an enormous sound stage and even in that large room could have used more space.  Seemed like they never broke a sweat.  

One of the best I have ever heard, top tier.  But, oh kind reader, please be aware that every driver in the system had been upgraded by their chief speaker designer, Chris Brunhaven (sic?).  Along with custom x-overs and amps for the bass towers, so they were no where near "stock". 

I'm actually sort of surprised that so many people have heard them considering there were only 78 systems produced.

The late Corydon Johnson rebuilt the EMITS and EMIM’s.

Chris spec’d new Woofers from Parts Express and I believe did some Mods to eliminate the “Servo” (accelerometer) part of the system. Paul did a Video on them about a year or so ago.

Ive listened to both Paul’s system at the factory and Corydon’s before he sold them after 40 years of ownership. Both were amazing and did all the Audiophile terms extremely well.   

Before he passed away, Corydon on his IRS V’s (purchased at Lyric HiFi also with ML-2’s on each channel) modified the EMIM’s so that they were a true fullrange driver thus eliminating the EMITS which he said were a pain in the Ass to rebuild. The Gentleman who bought the IRS V’s is currently extremely satisfied with the work Corydon did. The Woofer stacks were rebuilt (woofer surrounds reformed) but the “servo” stuff including BHK’s Amp to drive the stacks were untouched and 100% operational.
