Page 10: Design Philosophy
The subtlety of the design process at this level of performance makes it impossible to easily explain all of the advantages inherent in the 40.0. However, we present here an overview to give you an understanding of some of its unique features and an idea of the listening experience you can expect. - Page 11 Coda. As with all high-power ampli ers, heat dissipation is important. The 40.0 uses six massive aluminum heat sinks without fans for e cient, noiseless, and clean thermal relief. The thermal coe cient of the 40.0 heat sinks is one of the lowest and most e ective in the audio industry.
- Page 12 DESIGN PHILOSOPHY II. Material Quality The amplifier’s chassis is made from machined aluminum. All exterior metal parts are anodized or powder coated for durability. Printed circuit boards are fiberglass epoxy with gold plating over a tin/nickel barrier. The gold layer will not corrode, while the barrier layer prevents the gold from migrating to the lower copper layer.

Page 14: Care And Handling
CARE AND HANDLING The interior of the amplifier requires no special care. If exterior cleaning beyond simple dusting is required, any dilute ammonia-based product is recommended. Do not use any abrasive rags, cleaners or chemical solvents on the amplifier. When handling the amplifier, take care not to mar the faceplate. Aluminum is a medium hardness metal and can be scratched by harder tool steels, and the grained surface can be easily marred if the amplifier is set face-down on a hard surface. -
