I like to get opinions/experiences that you had, whether there is a difference in audio quality/sonically in plugging the power amp to a power conditioner or the wall outlet. There has been some discrepancies in opinions o this. I know several power conditioners have an outlet specifically designed for current-hungry power amp, separate from the isolated outlets. For the purpose of warranty, I know that all equipments have to be plugged into the conditioners in order to be in compliance with their terms and replacement policy, should electrical misfortunes happened. But, I've been told by several reputable dealers to plug power amp directly to the wall outlet for better results. thoughts? danke!
