I have received a barrage of emails from a Head-Fi Discussion regarding our Premier Silver USB cable. Here are few questions and answers:
Does your cable meet USB 2.0 standards?
- Yes. As stated in our Specifications on the web page (bottom line under Manufacturers: USB 2.0. Maximum data rate 32-bit 384 kHz (480 Mbps). Impedance: 90 Ohms. Wire gauge: 22 signal, 22 power.
- Supports high-resolution PCM, DSF, and DSD D-A converters with USB 2.0 'B' ports.
- Compatible with USB 1.0, 2.0, 3.0, 3.1 'A' computer ports.
- Our USB cable is supplied with standard A/B plugs. No mini or micro plug versions are available.
Would not a super high-speed USB 3.1 cable be superior?
- NO. USB DACs do not require a high speed data interface. They will work well at the highest data rates with USB 2.0 ports. Unless your DAC features 3.0, 3.1 ports or USB Type-C ports, a USB 2.0 cable will perform just as well.
How is it possible there is a sonic difference in a digital USB cable since there can be no data errors?
- Computer power supplies are dirty and noise induction into the signal leads is clearly audible. Our USB cable features discrete power and signal leads as well as excellent shielding. Quality USB connectors ensure a positive connection to avoid data errors.
Do air cores and fancy metal braiding really help the sound?
- Absolutely. Most USB cables use PVC insulated wire, PVC solid core structures, and PVC sheaths. This creates “dielectric polarization” which alters the magnetic field current. It is a form of distortion that can be clearly heard in critical listening tests. This effect does not create data errors but can contribute to sonic degradation similar to noise artifacts. This effect is even more pronounced in analog cables and is why we minimize dielectrics in our cable construction.
Sorry, but high-end USB cables are bunk!
- Not a question but a statement of belief. Cabledyne is one of many cable makers that build audiophile USB cables with customers that can hear the benefits. Our customer testimonials speak for themselves.
