The big difference between professional made Obsidian plinth
and amateurs made plinths are the dust cover which can be
positioned at whatever level and tonearm board which can be
easy fastened with 4 big screws . Those sell for 600 euro each
while their construction and quality can't be matched by any
of those ''alternative'' plinths. For my Kuzma Stabi Reference I
need to use an simple plastic sheet in order to protect the platter
from dust. The dust cover on my SL 1000,mk2 I need to be clean
each week. Without dust cover all this dust will be transferred to
to your LP's.
