Dear @rauliruegas,
Thank-you for the forum references. My choice of the word lifeless was more in haste then any proper assessment. I found the softer rubber Technics mat to put a soft-focus on the music; the small intricate details were missing; essentially the system was now over-damped.
Of the audio magazines - as you state, for sure Audio has/had the most technically founded (justified) papers.
Otherwise - one more good paper http://www.laudioexperience.fr/wp-content/uploads/2017/04/Bruel-Kjaer-Audible-Effects-of-Mechanical-..., and this one is specific to measured Audible Effects of Mechanical Resonances in Turntables and it is an interesting read.
Stay well
