YFS USB V2 CUSTOM AUDIOPHILE USB 2.0 CABLE
We here at YFS are proud to offer our very first USB digital interconnect. We call it the YFS USB-V2. Are you wondering which USB 2.0 cable to use in your computer audiophile system? We have the perfect solution. First, ask yourself a few quick questions. Would you hook up your CD transport with a cheap Chinese digital cable? Would you skimp on performance to save 50 bucks? I don't think so. It's the same idea when it comes to hooking your computer up to your DAC. Don't compromise performance by using a cheap Chinese USB cable between your music server and your DAC.
Many folks in the audiophile world claim USB cables do not make a difference. Have they tried various cables or are they just assuming there's no difference? We HAVE tried various cables and we GUARANTEE the YFS USB-V2 will beat ANY cheap Chinese USB cable out there! We don't feel our claim is wild or unjustified.
I want to touch on some factors we used to come up with our USB cable. The following is from our F.A.Q. section. Go there to read the entire article. Here is an excerpt:
The digital cable affects data transmission by distorting the square wave pulse, reducing the amplitude, causing phase (time) delay, and coupling noise into the data stream. This ultimately leads to detection threshold errors on the peripheral side of things which translates into lost or incorrect bits.
So our goal is to maintain signal integrity at high frequency (Fast edges translate into high frequencies, remember our old friend Fourier). The first step is to optimize cable physical geometry, including placement of conductors, shielding, and grounding. Transmit/receive termination admittance, cable distributed capacitance/inductance, and EMI/EMC are considered in the data channel optimization. Power channel wiring employs shielded oversized conductors to reduce loses in longer cables. Both channels have 93% silver plated copper braided shields. One version also includes a 100% coverage metalized Mylar shield in addition to the braided shield (helps with EMI/EMC requirements but didn’t affect sound in our tests). Separate shield for data and power channels reduces BER by decoupling power supply noise from the data channel. A very important aspect of any cable design is the material choice, both conductor and dielectric. Our material selection is based on years of experience in the aerospace industry where signal integrity and low noise are paramount. Employing the proper dielectric (optimized dielectric constant /dielectric absorption) makes a huge difference in waveform integrity. (and it’s NOT Teflon like most people think!)
