I am totally in favor of tweaking to get the most out of a system. But not every tweak works, or works well enough to be worth good money. This one it seems has been around many years now. Wonder what's the verdict?
I went to highend-electronics to check out user reviews.

Compare that with the reviews for the similarly priced FEQ from Synergistic Research
https://highend-electronics.com/products/synergistic-research-feq-x4Or the many outstanding reviews of the much less expensive HFT
https://highend-electronics.com/products/sr-hft-high-frequency-transformer?variant=4921086115869Pages of reviews. All excellent. And these come with a 30-day no questions return.
Odds are Speaker Clarifiers probably will do something. Question is, are they worth what they cost? Sure seems there'd be more buyer reviews if they were. But hey, buy a pair, let us know!
