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)

I am running Aktiv Ninkas, but in an all Linn system. Instead of daisy chaining the amps, I am running both amps (LK140) out of the preamp (Kolektor). I am using the Linn supplied PCs and ICs (black). The PCs are plugged into a PS Audio Juice Bar and then in their wall outlet.

When I went Aktiv, the first thing I noticed was more music at lower volumes (more information), better bass response and the tune was easier to follow. I had to reposition the speakers by pulling them further out from the wall and re-toeing them in. Prior to moving them away from the wall, the bass was too boomy and too much. I believe I moved them out an additional 5 inches or so. I can post the distances before and after, but it depends upon your room size and listening distance, obviously.

To your questions: 1. I did not notice the "too much information" as you describe. Again, I found there was more music at lower volumes, but when a band starts playing I don’t find it drowns out the vocals.

2. I purchased my cards second hand, so I cannot comment on burn in. I am sure these cards have burn in like all other equipment is supposed to have, but I can not comment what might change as they burn in. I did find I needed to “get used to” the Aktiv sound. It was a change for the better IMO. It is a lot more detailed and showed a lot more faults in the recording of CDs. Some people have commented Aktiv can be fatiguing, but I don’t find it so.

3. I have not really messed around with different ICs other than Linn black versus silver. I would recommend trying to split the signal at the preamp to see if that helps the problem. I remember reading in a different forum a discussion regarding which sounded better and the general consensus was using the additional outputs from the pre sounded better. I can switch mine over and report back if you would like.

Stuart:
My room is 17.2L x 11.2W x 8H. My listening chair is around the 13-14 foot mark.

Measuring from the top of the speaker to the back wall: Passively, the Ninkas were installed by my local dealer who set them up 3 3/16” from the wall on “the inside” of speakers and 3 3/4” from the wall on “the outside” of the speakers. The toe in being almost ½ inch. When going Aktiv, I moved them to 8” from the wall on the inside and 8 1/4” from the wall on the outside. My toe in is just the 1/4 inch. I have tried greater toe in, but didn’t think the speakers disappeared as well.

Measuring from the Kustone bases: Aktiv, the distance between the two speakers is 57 1/2”. I am measuring from the front, inner corner of the two speaker bases. The left speaker is 28 1/2” from the left wall and the right speaker is 29 3/4” from the right wall. I am measuring from the wall to the outer corner of the base on each speaker.

I hope these measurements make sense and aren’t too confusing.

I think I can understand what you are hearing and you aren't necessarily complaining. I have noticed listening to some CDs Aktiv, instruments are more pronounced than previously. This can some times be distracting. I found this with the Barenaked Ladies CD, Maroon. The cymbals in one of the songs are really pronounced. . I think this is why some people feel Aktiv systems are fatiguing. There is a lot of sharp, crisp, detail without much forgiveness. I dunno. I love it. My ears have "burned in" ;) to loving the Aktiv reproduction of music. I think the tune is easier to follow.

Also, don't forget you can control the treble volume on the treble card. This may help, or may not.

I came across this old posting in another forum and thought you might want another opinion:
___________
Passive with standard bases needed to be close to the rear wall (about 7inches) to get "even" sound

Activ (2xLK140) with standard bases needed to be pulled into the room(about 11 inches)to remove bass boom

Activ (2xLK140) with (Santa's)polymer bases I needed to move them back towards the rear wall again to bring the bass back in (about 9 inches)
