Hi Alb24, I am using a Sonic Frontiers Line 2SE on my Krell FPB 200 and to say the least I'm pretty happy with the combination.
The minor adjustment that you mentioned is just a couple of jumpers that you need to take out and it takes 5 minutes it's just a matter of opening the top and locating the two jumpers. Krell had faxed me a diagram and intruction on how to do it, email me and I'll fax them to you if you're interested. If you're worried it may change the sound of your amp, don't be at least I never notice any on mine plus the warranty on your Krell amp is intact. Remember Krell will not fix your amp under warranty if the damage is cause by a pre amp with high DC offset.
Happy Listening.
