A Copernican View of the Turntable System

Once again this site rejects my long posting so I need to post it via this link to my 'Systems' page

All the following readouts contain vibrations of higher frequencies (mostly above 1000Hz) which are able to be absorbed, reflected or dissipated (to a degree) within the normal provinces of footers, stands, isolation devices and depending on design....within the plinth, platter, feet and mass of the particular turntable.
Here is a readout with the Isolation 'OFF' and the turntable REVOLVING.
Here is a readout with the Isolation 'ON' and the turntable REVOLVING.
Here is a readout with the Isolation 'OFF' and MUSIC PLAYING.
Here is a readout with the Isolation 'ON' and MUSIC PLAYING.
Halcro,

If I look at the Herzan readouts with and without the music playing, the correction is different. This would appear to show that the Herzan is effectively modifying the music signal playback due to the vibrations of the stylus by imparting a corrective response that has taken into account stylus vibration generated into the platter/TT. Thus the measurement of the groove by the stylus is no longer accurate because the Herzan is responding to the music and thus polluting the signal..

Could you give some consideration and response, thanks.

Eddy Driessen is one of the ''Dutch grandmastrs'' known by

his ''Pluto'' TT's and tonearms. I am not the right person to

comment on TT's designs but his ''form follows function''

TT's looks to me to satisfy most conditions mentioned in this thread.

Not so....
The added vibrations with music playing is purely Airborne Sound Transmission.
HERE is a readout with the Isolation ’OFF’ a record playing but the sound MUTE.
And HERE is a readout with the Isolation ’ON’ a record playing and the sound MUTE.

Thanks for that - agreed.
Ideal would be TT in separate annex away from airborne vibrations.
For those that can't afford the Herzan I have previously had some success with sound absorption panels behind the TT in resonant environments.

Very cool Henry.   did you get a decent price for the Herzan and where did your source it from?
  I can pm you for ultimate details.
