Choosing a Digital Cable
For maximum performance we recommend using an ST glass-optical
cable, which can be purchased from your Wadia dealer, for any
digital audio connections. Wadia Digital was the first company to use
glass fiber-optic data-transmission in digital audio and we believe that
it offers the best performance of all the available options. Based on our
experience, here is a list of digital interface methods in descending
order of performance:
1. ST-type Glass optical (as implemented by Wadia, with high
quality glass-optical cable)
2. AES/EBU using XLR connector
3. Coaxial S/PDIF cable using BNC connector
4. Coaxial S/PDIF cable using RCA connector
5. TOSLINK plastic-optical cable
The quality of any of these transmission methods depends on the
quality of the cable and the sophistication of the transmitter and
receiver. For example, a high-quality coaxial S/PDIF cable can
outperform a low-quality AES/EBU cable. A high-quality AES/EBU cable
may outperform a poorly implemented glass-optical system
If you are using a coaxial S/PDIF connection, we recommend having
the cable terminated with a BNC connector. This will provide higher
performance than an RCA connector. Your Wadia 301 CD input kit
comes with an RCA/BNC adapter that can be used for experimentation
between different types of coaxial S/PDIF cables.
Again, we highly recommend that you take advantage of your dealer’s
experience and, most importantly, trust your ears.
Connecting to the Digital Inputs or Output
To connect to either the digital inputs or output of the Wadia 301 CD,
simply connect the appropriate digital input or output to the outboard
component.
