"The technicians of Technics designed a special base for the SP10 mk2 which was also used for the SP10 mk3. It was made of obsidian (volcanic glass) which had a nice shape and was beautifully polished. Hi-Fi Choice from Great Britain however reported that the bass was somewhat slender and that there was some shallowness in the mid and upper mid frequency region. This is certainly caused by the amorphous "structure" of volcanic glass. Glass sometimes used for plinths and platters has this characteristic. "
Mais je suppose que tu connais :
"Better not use corian as it has a frequency curve with emphasis on high frequencies. The properties of corian are also not always as desired because the percentages of aluminum varies.
And better not use MDF, also because of its odd frequency characteristic which shows uneven sonic qualities with emphasis in the lower mid area. This anomaly may disappear when you use many layers and construct a very heavy base. But then the fact remains that it is in fact "dust" pressed and bonded together.
I myself am not an advocate of too heavy plinths made of materials with a high density. Better choose the material and the volume in accordance with speed of sound and an even characteristic without abrupt filtering of the signal. Look for the data of density, sound propagation, stiffness, etc. in The practicing Scientist's Handbook by Alfred J. Moses (Van Nostrand Reinhold Company, New York, 1978).
The frequency of the isolating rubber feet or springs supporting the base plate (the SP10mk2 unit included) should preferably be between 2 and 4 Hz."

Si j'en avais une et que j'étais bricoleur, je testerais bien leur version suspendue .
