  • Simply put, both protect against certain types of interference in different ways, and each is effective in ways that the other is not.

    Mesh shielding is going to help prevent electrical interference from being introduced via the wire itself from an external source. Like other cables carrying signal and running very near/parallel, or electromagnetic fields generated from other devices, certain electrical components, household appliances, etc.

    The ferrite beads protect against radio-frequency interference (RFI) via induction, acting like low-pass filters which attenuate specific bandwidths of very high frequency signals. Essentially, they intercept and absorb high-frequency electrical noise, and convert that energy into a small amount of heat instead of letting it pass through further down the signal path. This kind of interference can be from an external source, or generated internally from the various electronics/components in the signal path (which mesh shielding would do nothing to protect against). They also help dissipate any RFI that the mesh shielding itself may be carrying, so you often see both ferrite beads and mesh/foil shielding, like on laptop chargers or USB cables for example.



  • He’s talking about the electromagnetic shielding in a cable, not the contact-points. Usually a copper mesh sheath housed underneath the outer-most rubbery layer and runs around and along the entire length of the signal-carrying wires inside the cable. Works like a Faraday cage, helps prevent electromagnetic interference from large power sources, other unshielded cables running parallel, or anything else that can generate an electromagnetic field near the cable.

    Very important to protect signal integrity, widely used even outside the audiophile world (although there are of course plenty of audiophile gimmicks related to shielding).

    Basically, if you have a bunch of live unshielded cables bundled and zip-tied together along with your speaker wire, you’ll definitely hear it. Run the signal through an oscilloscope, and you’ll even see it





  • Want to save this thread for later, may as well name a couple as well

    The Faceless - Planetary Duality. Technical death metal album that found an outstanding balance between technically-impressive musicianship, interesting compositional intricacacies, and raw primal brutality. Nothing scratches that itch like this album does for me. And if you’re into drums, Alex Rudinger’s drumming in Xenochrist is wholly and entirely inhuman. The dude is an octopus trapped in a man’s body. I’d recommend watching his Xenochrist drum playthrough video if you’re particularly interested

    Infected Mushroom - Converting Vegetarians. These two guys are absolute wizards of music production, and this album showcases their insane ability to bring out such colorful personalities from their meticulously crafted synth leads, through gradual and dramatic evolution… Which they usually do in a familiar psy-trance setting. But the “chill side” half of this album accomplishes this wonderfully in a unique, much more relaxed, low-tempo style that I’m genuinely struggling to find words to describe
