Let the amp run in for a few hours, they do gain focus after the new tubes get some hours on them. Also changing the pre-amp tubes can gain good results so if you keep the amp it can be better than it is today. The Krells are good amps so it will take the right tube amp with the right tubes to get up to that level.
