i own three turntables, and own -2- CS Port IME1’s and a single DS Audio ion-001.
so one for each turntable.
the advantages of the stand mounted version is continuous emitting of negative ions to reduce static and lower noise. and you turn them on and they are passive. just play records.
the only challenge is finding a spot on your plinth or rack to set them in proper proximity so you get full effectiveness. which is why i own 2 different types.
hand held products such as the Destat III provide temporary improvement, less than a full side (5 to 10 minutes). and require a pre-treatment process for every side you play. that will get old quickly. i have three or four older versions of the Destat III in my tweak drawer gathering dust. then it’s a door stop, effectively.
cheap tweaks you never use are expensive.
better tweaks you really use and make the music sound better every time are priceless.
