All great advice on the 5140s. I had mine running active with 5105's, and the jump in quality is very large. I found the improvement to be across the board, and for me, the jump in quality of the voice was most noticable.
I believe 5140's, active or not, will fill your size room with great sound. In particular, with a subwoofer.
I suspect there are plenty of 5140 active cards available, a good Linn dealer should have them. Not sure if they would work on the Chakra's though. I have a complete set that would go into 5105's, and I have the 5105's. I believe you could go active with very low cost buying 2x5105 and the 6 active cards.
