Puritan vs IsoTek vs inakustik

I love my PSM156. I actually did measurements on mine to make sure it actually worked. It reduced my line noise by almost 75% in addition to providing surge protection.

Kinki Studio/Vinshine TaiHang is very good, esp for the money. Less than $2K.

I read all the glowing reviews of the Puritan as well. It does make wonder if there was something wrong it’s the one that I had.

I have had the exact opposite experience of @zlone. When I removed the P15 and introduced the Puritan, I couldn't believe the impact. Everything got better, making me feel like the P15 was doing nothing.

@lancelock Wow, interesting. Makes me think even more that I may have had a faulty unit. The impact of the P15 was subtle to be sure, definitely not a wow factor. But I think I have pretty good power to start, and it just gives me consistency.
