Guys... your input is appreciated! To make a long story short, I bought a pair of RT2000i's a year or two ago. At the same time I bought what I thought was a CS400i to match, only I got a CS40i shipped to me. At the time I decided to keep it, thinking I got the newer model for less. Now I am not too impressed with the match to my RT2000i's. Do you think I should trade my CSi40 in for a CS400i, or is it worth the hassle?
