In honor of the recent introduction of our NEW Blue Heaven 3 Digital cables, we thought it would be helpful to share some of our most frequently asked questions around digital cables. Hopefully, these will help you demystify digital cables as a whole and give you an insight into what makes Nordost digital cables, from Leif 3 all the way up to Odin Gold, special!

Q: If a digital signal is basically just 1s and 0s, how can audiophile USB cables make an audible difference?
A: The signal that flows through a USB cable is actually analog in nature. It’s composed of high-speed square waves that represent 1s and 0s. Losses in the shape and speed of those square waves can cause equipment like DACs to misinterpret the conversion to an analog musical signal and cause distortion.

Q: Are Nordost Ethernet cables shielded?
A: Yes, because of how susceptible they are to RF interference, shielding is something we took to new levels when we designed ALL of our Ethernet cables. The twisted pairs inside our Ethernet cables have their own shielding as well as a dual braid shield over the cable assembly.

Q: Why do Nordost 75 ohm digital cables come with BNC to RCA adaptors?
A: The correct termination for true 75 ohm impedance is always a BNC connector because of the mechanical spacing of the center conductor relative to the outer insulation. If you terminate directly to an RCA connector, you can’t maintain that impedance. We’ve found that keeping the integrity of the 75 ohm cable with a BNC termination and using an RCA adaptor always provides better sonic results than a direct RCA termination. It also means the cable can be used easily as a clocking cable, which typically uses BNC connections for superior performance.

Q: What technologies differentiate Nordost USB 2.0 cables from their competitors’?
A: Nordost cables utilize high-purity FEP insulation with either Micro Mono-Filament or Dual Mono-Filament technology, which enhances the speed of transmission, as well as advanced shielding techniques that maintain the integrity of the signal. These technologies allow our cables to perform to spec, even at extended lengths, with no loss of information. Additionally, the connectors of our Blue Heaven 3 USB 2.0 Cable are constructed using ESD material, which dissipates electrostatic charges from the cable and prevents those charges from ever building up, before they can negatively impact performance.
