I have been using these with my large Horn speakers for 2 years. Everything sounds better. Bass, mids etc. I brought mine to friends 2 weeks ago. They did the same for their Von Schweikerts. These are not snake oil. Compared to upgrading cables these make a bigger difference. IMHO. I run mine at a 3 which seems to be most folks sweet spot. With my friends VS 4 seemed to sound better with the silk dome tweeters.
