Isolation pucks

[sam1000]

Last week I read a report on the homepage "The Audiophile Man" of new isolation feed, "DF DAMPING ISOLATION FEET FROM SOUNDECK"! Since the price is not high, I ordered a set, after 5 days the parts arrived. I installed and tested the parts under the Devialet. What immediately struck was more quiet in the background, less noise floor and more precision in the instruments. I only tested for a short time, longer test follows. I have already tested other feet for a price that is only marginal changes. At the price until I'm really surprised !!

Thanks. Is it possible for you to place them under your speaker? And then place your phone on top of the speaker running either Seismometer or Seismograph app. Then thump the floor like shown in the link below.
