Limited Titanium NAB Isolator by Studio Alchemist

        Limited edition of NAB Isolator by Titanium alloy is undergoing.  Titanium alloy is always a amazing material for audiophile due to its superior sonic character and I am wondering to know the performance difference between titanium and regular aluminum version!
        *Density of titanium alloy is about 4.6g/cm3 and aluminum is about 2.7g/cm3.
