I heard Seismion platforms under a couple of amps and a turntable. I’m sorry to say that but it sucks the life out the music and reduce dynamics dramatically. If you have a bass and/or midbass thumb because of speakers or room you can be fooled by reduced dynamics but it is impossible to like the sound. Surprisingly when you turn it off it starts to sound better. Of course not as good as any other passive platform. I’m glad that it works for many people. Please listen again.
BTW there can be many question that something went wrong with our trial. No, we tried Seismion platforms the correct way, nothing was wrong, no component, speakers, room, electricity or our ears have problems.
