I appreciate your advise and am considering trying a dezorel "brick" on the amp down the line. However, the dezorel does not offer surge protection and i am trying to find out more about the krell's need for such. They just e-mail me that i don't need to add either. So at this time i will trust that no additional surge protection is needed, barring a direct hit. With regards to line conditioning, well as they say, "the proof is in the pudding". We shall see in testing whether the sound is improved or not. In the meantime plugged directly to the 20-amp line this amp sounds mighty sweet. Enjoy the music!
