Soon time to upgrade from the HD650's. Had them since 2007, used them every day from 1 hours to 24 hours straight gaming/music/tvseries sessions. They have seen their share deal of wear, so im getting abit tierd of the sound of them.   What would be a good upgrade? 500-600$ budget.  ...

Hi everyone, first time poster here and a complete noob! I am concidering to buy an headphone amp for my Hd-650's since my Z-5500 dosnt do them justice.   Have been checking Little Dot MK III and Beresford TC-7510, anyone have any other suggestions? :) Would like to hover around 300$...
