Linn Ninkas now Aktiv but a couple questions.

Three days with the aktiv set-up and K400 wire. Nice. Got a few questions though. (1) Did anyone initially experience the sense that there was almost too much information? The set-up sounds wonderful in simpler passages like a voice and guitar but tends to get kinda swallowed up when the rest of the band kicks in. It might just be my room. Though the effect may be linked to the following questions as it seems to be softening.(or is it just my head that's getting soft?)(2) Is there a burn-in time for the cards? (3) I noticed quite a difference between hooking up the output from the pre into the bass amp first then from there to the treble amp than the opposite. Problem may be that my IC's are not the same as whatever is hooked up first sounds better The pre out has yamamura m5000 the other, between the amps, is a .6m blue heaven. Any tips or suggestions? What about splitting at the pre out? What kind of PC's and IC's are you others using successfully? (I have a cary slp-50a pre and rega planet2000 cdp, with synegistic re. master coupler pc's) Look forward to your answers and thanks for your past help getting me here and in advance for any suggestions. PS my test cd right now is Aimee Mann's "Lost in Space" (I'm a bit timid about breaking out the orchestral works until I get all this sorted)
