II. Parts' Quality
1.Finishes - All exterior and interior metal parts are anodized. While paint may be more impact resistant, the anodized surface is more resistant to solvents and prevents corrosion. Moreover, the anodized parts' appearance can be enhanced by either graining or
2.Circuit Board - 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.
4.Capacitors - All capacitors have been eliminated where possible on the basis 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) to be found in this product. Very high quality dual FETs are the only source of voltage gain and 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.Potentiometers - The volume controls are conductive plastic. These pots track with little error and are totally neutral.
7.Connectors - Coda employs a standard RCA configuration with a gold plated case. The balanced connectors are Neutriks from Switzerland.
8.Wire - All signal wire has been eliminated whenever possible. Where wire is used, Coda employs silver plated copper, 141 strand, 18 guage wire with a silicone insulation.
