Mechanical stability in audio systems, in practice, is seriously misunderstood. Every millimeter of signal path or AC cabling is susceptible to vibration – every component in your equipment rack, too – a vibration that manifests as spurious noise and distortion. For years, we have talked about isolating systems from the outside world while ignoring that the AC supply and the components within the equipment rack are significant sources of mechanical energy – energy located right where the signal is.
Evacuating and dissipating self-generated vibrational noise is a critical contributor to eliminating the noise that will rob your system of clarity, correct timing, and dynamic range. Isolation from the outside world is essential, but steps to reduce vibrational noise from one component are more critical. System support and interface are essential considerations, not accessories and certainly not luxuries.
