Help build setup for Thrash-Metalcore

I want to find a sound rich colors, and not just loud and fast. I tried the Prima Luna DiaLogue One, Audio Research V50 with Klipsch Cornwall and Sonus Faber.These components play any music. But when I put the Slayer, the sound disappeared. I can not understand what's wrong? I Just loss my way.

We all do.Those are very good components.Try a different source?Not sure.You give tete info of room and more.Maybe moving rugs,furniture,speakers,ahhhhhhhhhhhhh,I dont know....but good luck,B

On Wednesday, I will try again Prima Luna

I've been enjoying my metal more than ever lately. I purchased a used Bedini 150 MkII on ebay & paired it with an old Lazarus Cascade Basic. Speakers are little Snell Type K/IIs, sub is a Snell Basis 150. I get more responses out of people who are dumbfounded by the sheer brutality of my setup. They can't believe the little Snells & sub make that great music!! You don't need "Bigger is Better!" BTBAM & Machine Head never sounded so good!!
