linn passive to aktiv, confused


i recently changed my linn passive system (genki, kolektor, lk140, ninka, single wire) to aktiv (added an lk140). i hardly recognize my system it sounds so different. there is much less treble, more bass and it seems to resonate in the room more. the texture is perhaps a little more gritty, however also more detailed. the treble is more transparent, but also sounds receded to me.

i switched the boards on the back of the speakers; does the orientation of the lower (hidden) board matter? the treble says "reverse polarity" and i hooked up + and - marked on the speaker consistent with the amp.

these are all used components and should not require a "burn in" period, right? or do i just need to get used to it? the bottom line is the speakers are more impressive technically to my ear but possibly less musical. it still sounds incredible compared to anything else i have owned.

comments? thanks!

Linn has made many speakers that can go Aktiv (as they spell it). The answer to your question is best answered by someone that has the speakers you use. If you are using Keilidh's then shoot me an email and I'll give you my phone number. Otherwise, I'd suggest you more acurately describe what you have. Two amps or three? Tunebox or the crossovers in the amplifiers? Older speakers with outboard crossovers? Lastly, if they are used, did you consult with the seller? He should have walked you through this.
My Aktiv cards have nine dip switches at .5 db each for a total of 3 db. There are a number of differences between Aktiv configuration through the years. Please post what equipment you have and you'll get some good help. An additional thought is to take a closer look at your interconnects and speaker cables. It's easy to make a mistake there. If you have the mid/bass out of phase and the tweeters in phase it will sound as you describe.
I think I remember hearing that there are different cards made for the same speaker. If one card went bad and the old style was no longer available you had to replace both cards. That is my suspicion. Please send an email to Linn tech support asking about this. I hope I'm wrong. While the speakers certainly sound different in Aktiv vs. Passive I doubt if you would have posted this if they sounded correct. Linn may take a day to answer but they will answer.
