I was just wondering, why do they have extreme frequency responce on some pres and amps. Say like the Audio Research Reference 3 line preamp(0.2hz - 200khz), when most of the high end speakers take on something like 18hz - 80khz, and on top of it most everyones mics only recrod 20hz - 20khz like a neumann u87 ai or another high end condensor mic. Also like movie guys don't as often use great mics just one good enough to do some filming. So forth and so on, you guys get me. Like I've heard systems close to this they do sound great, but I dont get it, isnt it overkill to do such like that?

SAS Audio Labs is pleased to announce the introduction of the 11A Reference line preamplifier. Please feel free to ask questions.

This isn't the "Price is Right" show. If you have to ask than just go to some retail outlet and let the salesperson help you. I hate these types of threads.
