Sometimes a tiny bit of microphonics is not all bad (makes music sterile/lifeless with the rings). It may really depend on whether you have a microphonic problem. If not, then you'll may not notice anything with the rings. No different than those with clean AC power to start with find no benefit with AC filters; those with a very stable rack find no benefit with issolation devices; those with a well made CD player find to benefit from a separate jitter device; and so on.
