II. Parts' Quality
1. Finishes - All exterior metal parts are anodized or powder coated. Anodizing for its
multiple finishing and powder coating for durability.
2. Circuit Boards - Circuit boards are fiberglass epoxy with gold plating over a tin/nickel
barrier. This gold layer will not corrode, while the barrier plate prevents the gold from
migrating to the lower copper layer and detracting from its appearance.
3. Resistors - All are high reliability metal film 1% resistors for 1/4 watt and 5% for 1 watt.
4. Capacitors - All capacitors have been eliminated where possible on the premise that
“no cap is better than the best cap.” The only electrolytics used are in the power supply
where large numbers provide enormous filtering capacitance for the supply.
5. Semiconductors - There are no integrated circuits (IC) in the signal path. Very high
quality dual FETs were selected for their superb noise performance and precision
matching. The remaining semiconductors are also of very high quality, each possessing
parameters ideally suited for the specific application.
6. Connectors - Coda employs a standard RCA configuration with a gold plated case.
The XLR input and output connectors are manufactured by Neutrik of Switzerland.
Speaker connecters are also gold plated.
7. Wire - All signal wire has been eliminated whenever possible. Where wire is used,
Coda employs solid silver and silver plated copper, 141 strand, 18 guage wire with a
silicone insulation.
