Yes I heard the fr 30 and understand why Paul had to let go of irs v. His statement was in his video the only time irs beat fr30 was in high end classical music with big sound .forgive me if I'm missquote.he may be a salesman but look who he has working with him some engineer that knows how to make stealth planes dissapear.in sinus surgery we use trickle down technology from image guidance off stealth bommer. It shows within 1 mm of where your at.when your removing tumors off the floor of brain eye socket carotid artery ect you want these genius technology.the irs v is so large it's hard to get in people's environment.the ps pr 30 cris helped with .his legacy has relationship with bohlenger graebener but took it a higher level with teonix or textreme in the ribbon/planner speakers.ive put over 1 kw in those > 100db and they are fantastic. I have the irs v and I currently try amp them with electronic crossovers. Ps audio has always answered my questions cris has been priceless as was paul.i took the tour and you should as well you won't regret it. My fr 30 run with bhk 600 another great designrr.i miss bascom king and arnie nudel.dont miss you chance to meet Paul in a tour.i take care of patients who work at a nuclear think tank they are brilliant.my father is a nuclear physicst.its trickle down technology.enjoy the music.
