The Catalyst series of switches are expensive for a reason - it reflects the quality of the components and quality of engineering. They are designed to work as part of large systems with hundreds of other network components all located in the same place. To make this reliable they are designed to minimise uncontrolled interactions with other components (such as excessive latency, bandwidth limitations and electrical noise). These design features are, I believe, where we see the benefit due to the minimisation of the uncontrolled interaction with the network interface of the Naim streamers.
Are they specifically engineered in this way Huge or are they just built to a higher standard than the usual consumer grade kit to meet the more stringent reliability requirements in the professional sector ?
