To fight aluminum tweeters-try different tubes? What do you have in there now?
I would have to say the speakers (aluminum tweeters). To me speakers make the biggest difference. They all have a very specific sound. It's what sound you prefer.

That being said I have a tube integrated and some tubes are definitely brighter than others. Not by that much but my Ei KT90's are very bright in the upper mids and highs.

Just my opinion
