I don't think there will be any drop in Evo series prices... The rumoured new A-class line of Krells will be, in terms of concept, some kind of replacement to previous AV separates. The flagship Solo-575 monoblock will cost $11275 per piece, which is cheaper than the smallest Evo-e monoblock (Evo-400e, $12000 per piece)...
