Post Subject: Acive versus passivePosted by Purite Audio on: 6/20/2014

Paul the UK Accurion distributor was kind enough to bring a P4 same internally as their 'Silencer' he also bought some accelerometers , we were able to measure the turntable directly on its usual isolation shelf, (GPA Monaco) and then on the active isolation platform.To cut to the chase the bass did sound tighter with the active isolation, but my wooden floor is not ideal.A solid concrete floor ,a solid welded metal table and the turntable placed directly on to the isolator would be the idealThe Spiers Robertson rolling air diaphragm platform is much more reasonably priced and appears to be more suitable for domestic HiFi.it doesn't really start to attenuate until around 4Hz but again subjectively bass is tighter in fact the whole spectrum is sharper.Certainly worth investigating if you use a non suspended turntable.Keith.
