So you say you've been out of HI-Fi for a while? And the first thing your asking about is a Power conditioner? I say Dump it! Ive never used a power conditioner nor will I start any time soon after 40 years of having stereo systems of all SQ levels. Any decent systems amplifiers are going to have fully regulated power supplies so it makes me laugh when I see people spending a lot of money for these conditioners that literally rob the life out of your systems sound!
