IsoTek is a good start to explore power conditioning. That’s all they do and they do it extremely well. There are so many approaches to cleaning incoming power, starting with dedicated power lines.
I’ve tried many popular and big brands power conditioners costing upto $20K. While they effectively lowers the noise floor, each of them added some sort of coloration. If you own a high resolution system, you can easily discern changes to overall transparency, tonality, dynamics, etc. each time you introduce a new element. While I appreciated the next level of reduced noise floor, I did not care for coloration being added to the sound.
Next, I decided to try transformer based power conditioning. To my surprise, it did some things better and more importantly added zero coloration. I have two dedicated lines in my audio room so that helps but plugging my electronics directly vs power conditioner netted in more transparency and increased dynamics. The longer I listened the more I was drawn into music. Music simply sounded more alive.. I was over the moon with what I was hearing for a fraction of price but more importantly, no coloration. Each note rendering effortlessly without accentuating any element around a central note. It’s more explosive on loud passages and quieter on quiet passages. The scale of the music is also more diverse, some recordings sound bigger, others smaller.
A good power conditioner reduces or completely eliminates unwanted RF and crud that comes in from the power grid. You need to find one that does it with least bit of coloration to the music.
