I have had a lot of Linn gear over the years, and I would not associate the problem you describe as being a characteristic of the electronics you have. I am not familiar with your speakers, and if you like them and want to keep them, my suggestion is that while you could tweak the sound with cables, that may be medicine worse than the disease. Another idea is to use a quality power conditioner, which will lower the noise floor, and that really opens up the midrange of any system. But I think a better approach would be to upgrade your amp. The LK85 is a nice amp, but it is not that powerful. If your speakers are a difficult load (low impedance and high phase angle), and/or if your room is large and/or, especially, if this problem gets noticeably worse as your turn up the volume, then I guess your LK85 is running out of gas. You might be able to bi-amp with another LK85, or go with the Linn monoblocks (LK140, I think). Maybe best of all is to look over this site for a gently-used Klout. That's an amp that that absolutely clamps your woofers, and should help the transition from woofer to midrange or tweeter.
