I did not use the 990 with Klipsch. I used Mcintosh with it. Everyone who has watched a movie recently has said it sounds better than ever. Most reactions are Wow, did you change something. Yes, I swapped out a $15000 piece of gear for a $1100 one. HAHA. Don't get me wrong I love the Meridian. I just don't agree with the people that say the 990 is a great bang for the buck, It is a great processor period. Just because the Meridian was so expensive does not mean it is that much better in sound quality.
