Modular rack systems also make it easy to add components in the future. They may seem relatively unimportant compared to the rest of the equipment, but cables and interconnects can make a difference between a good sounding system and a great sounding system. This is true on any size system from the low end to the highest quality. The signals between components and speakers need to flow unrestricted or the output will suffer. Cables should be a heavy gauge and the connectors should be gold plated.
Most electronic equipment has a remote control .
But you still need to be able to control all those devices. If you happen to purchase all your equipment from the same manufacturer, you might be able to control everything from the receiver remote. But most people don't buy everything from one manufacturer and that's where a universal remote comes in. There are a number of sophisticated systems out there that will not only do the job but make things a little simpler. A high-end touchpad system we installed includes a tabletop device with a large screen programmed to control each component.
