Not at all. The LX521 calls for 8 to 10 channels at 60wpc. I run a 12 channel B&K AV1260 which meets that spec. It retails for about $1200. Linkwitz recommends an ATI amp that is also a 12 channel amp that retails at $1600 or so. I see the B&K AV1260 amps going for $500 and less on EBay all the time.
So no. The multi-amplification issue isn't a problem. You're welcome to use more expensive amps, but it isn't necessary.
