Does that mean these devices have no use and are snake oil? From previous experience and I have tried quite a few over the years, they can and do change the sound somewhat. That term "somewhat" is left up to the interpretation of the end user.

Best approach is a "home audition" to determine if power conditioning, filtering or regeneration will benefit your particular case. With a return policy in place that is. Many manufacturers are starting to embrace that type of an approach and I would consider that fair, logical and honest.

I agree, in home with your gear is the only way to know what your going to get. I recently acquired a P5 and when compared to my Shunyata Talos I preferred the Talos. That however doesn't mean the Shunyata is better the the P5. If simply means that with my setup the Shunyata gives me the sound I prefer.
