Ok. My room is 12X28 and the 2A3 Paramours take the Pi's louder than I can listen. I've tried cutting off the Pi's at 40hz and used a really deep sub and preferred the Pi's alone. It's not just that they go deep and have dynamics you'll never hear on Kestrels or Paradigms or Magnepans, etc but the one thing that really knocks me out is hearing, for the first time after many playings, the tuba distinctly along with the trombones, not just a brass section on the Janacek Sinfonietta. So include low distortion on the bottom, with Eminence Delta among the strengths. Still wondering about the mids. Possibly I'm still captive of the audiophile sickness and part of the reason I need to build the Pro's.This week I will finally add the woofer RC network, AB the Mapleshade and RS magnet wire cables and make the long awaited pronouncement (Garland, how did you ever set me up as some kind of authority, are you kidding, I'm waiting to hear from you!)
