A softer warmer amp will help if you already have an amp that is slightly bright like a Rotel. The Musical Fidelity Nu-Vista would be a wonderful alternative that would soften the highs a little but still sound incredible. If on a lesser budget, go with a NAD amp or even a cheaper yet Harman Kardon 2 channel which has a warm sound. Of course, if you don't like bright highs but still want detail, get some Dalis or even smoother yet Dynaudio speakers instead.
