I just had this pumped to +5. I had the front half of a hemispherical sound field. Clean, clean, clean. Can't take too much of it. Reference level is good for this tune. It gives me a 140 degree field at that setting. This is Firestick 4K into my Onk and into my 1500-2 for woofers and 1000-8 for all else.
