particular art equipment art

I am searching for a very good rack for my equipment and
i stumbled one particular art . Their design seem to be very
inquisitive and interesting- I wonder if they isolate sounds
as well as they look, and if they are worth the price the
company is asking.
the pARTicular racks vary in their ability to isolate sound, depending on the model and shelving material used. they are full-blown audio racks, not just arty looking furniture. i do not believe, however, that the pARTicular racks are as acoustically "dead" as those from zoethecus.
Just curious, what are they asking?
