Just got Audible Illusions L1, but it sound harsh

Yes, my B&W has a metal tweeters. It is a bit hard to upgrade or try out different speakers due to its size. The next speaker I want is B&W N802 .. but it is kind of expensive, and I want to pick up, so, I need to wait until it comes up.
As for the amp, I am tempted to get a McCormack DNA-1 or DNA-125. Again, waiting for a Rev A or deluxe version to come up. BTW, is it a good match with the L1? Other models I have been looking are Belles 150A, or Aragon 8008/4004. But from the reviews and comments, it seems the McCormack are better. And I just post another thread asking for the difference between the DNA-1 and DNA-125. But in the mean time, I will try another set of tube first, or some interconnect.

Gte357s, you are on the right track with the McCormacks. In fact I have used the AI L1 with an upgraded McCormack with great success. I have spoken very highly about the L1 in the forums. My reference to a mediocre preamp in comparison to a high quality amp has nothing to do with the L1 but was trying to point out that one quality component can improve the sound of the other. There is no perfect preamp but the L1 gets alot right. However the ultimate tube preamp would be one that has tube rectification (no solid state devices) and ultimately will dispense with even the slightest detectable grain, but may lack the dynamics of the L1. There are some sacrifices with any design.

I'm using the Audible Illusions L1 with a McCormack DNA-0.5 driving Vandersteen 2ce-sigs and am very happy with the combination.

The McCormack and the Belles are excellent. I'm not fond of the Aragon as I find it to be bright sounding. I don't believe the solidstate rectification is the problem.

it's hard for others who can't hear your system to pin down what's causing your problems, but Stereo5's concerns about metal dome tweeters would sure top my list of things to consider.
