If your already using copper ICs and speaker cables.Next step would be a speaker with a silk / textile dome tweeter. Preferable a 1st order crossover..I find the 1 st order gives you the highs/detail on most designs but doesn't throw them at you IMHO.In other words the highs are there just not in your face. Also if using the Linn you may want the speakers to be amplifier friendly.
Good Luck!
