Are Linn Tukans a bit on the bright side?


I have a new used all-Linn system with Tukans biamped with a Majik (bass) and an LK85 (tweeter), and noticed that, particularly after biamping, the Tukans sound ever so slightly bright/unforgiving/harsh at the top end (e.g. soprano voices). This made me wonder the following:

1. Are Tukans known to have a bright sound, or is it perhaps the components I'm using?

2. Is the brightness a result of biamping?

3. Is there a tweeter adjustment that can be made to mitigate top-end harshness?

4. Are there interconnects that could help (I'm using Linn's standard analogue interconnects but thinking about picking up some Linn silvers)? Any recommendations within reason?

5. Would a sub help?

Thanks.

Tukans are a bit bright, especially if you are used to a larger speaker. There is a tweeter adjustment (made by dealer). I would suggest room treatment first, ie. something on the side walls and on the wall behind listening spot.
I have an all Linn system including Tukans and I have used the Linn standard analogue interconnect as well as the Audioquest Python and Anaconda and found them all to be on the bright side. I found the Tara Labs Air series, especially the Air 1, work the best for me and helped with the brightness issue.
They sounded bright and a little dry when I heard them. I only listened to them once in an all Linn system.
Tukans CAN sound 'tin' in bright room, and it is interesting that nobody mentioned or asked about source component? If good analog or Linn's own Mimik or even better Karik CDP was used i believe that would alienate most of the problems. So, evaluate your room first, then source.
