"Ringing" is a myth.
Unless you plan to practice drumming on your stand during listening sessions, "ringing" DOES NOT OCCUR in a metal framed stand.What a rigid,spiked metal framed rack does do is to lower vibrational amplitude via the small points of contact with high energy sources providing an energy/vibration bottleneck.The natural resonant characteristic of steels will filter the energy into relatively high, primarily even order frequency bands that the shelf material and component "suspension" can more easily damp.Adding mass and damping material only provides the energy a storage medium where those energies are re-released back into the system at unpredicatable low frequency rates and over a longer timeframe, thus imposing itself into the music for a longer period before decaying and having greater power to disrupt component operation and the musical signal.Low frequencies have enormous power and cannot be stopped regardless of the amount of mass or type of damping material used.The remedy is to have structure that does not couple well to those frequency rates, hence the need for low mass design.
Stands from reputable manufacturers such as Standesign, Apollo,Mana, Audiotech, Sound Organisation, Target,etc., all accomplish the task very well. Their primary disadvantage has always stemed from the relatively simple shelving required to meet a broad market pricepoint rather than any imagined "ringing' problem.
