Bob, You were already 90+% of the way there, all it took was that last bit of fine tuning. I agree, they really are "locking in" beautifully now... As any Apogee owner will tell you, they really appreciate the last iota of attention, and reward you royally for the TLC. Nice job Bob, I'm really pleased for you with how well they match your equipment (DNA 500 ='s warp drive power with a dash of tube) and how well they're integrating into your room. Congratulations. Grant
