Although Crestron's multi-zone amps are over-priced (IMO), their audio pre-amp is one of the most versatile on the market. Because it's operation is controlled by the main processor's logic, you can program features that are very difficult, or even impossible, with other brands.

For example, you can have four satellite receivers, selectable from a single "Sat" button. The keypad can be configured so that the first available (not currently in use) receiver is automatically selected, or one press selects the first unit, two presses select the second, press and hold does something else, and so on.

That is only one of MANY possibilities. You can do all kinds of things, like "Party Mode", scheduled maximum volume levels (after 10pm, selected rooms can't exceed X percent), automatic shut-off, etc.

As for the RadioRa, I would definitely not recommend it for a new construction. While it's a nice solution for retrofit, the protocol is too limiting, and you're paying for technology (RF) that you really don't need (because you can run wires). As someone else suggested, it's possible to install a "limited" centralized system with only a few zones initially, and add more later -- just make sure the wiring is run appropriately.

If you still don't want to go that route, I'd choose HAI/OnQ's ALC system over the RA (for new construction). It can work with "normal" electrical wiring, and only needs an additional Cat-5 to each switch location. You can install regular switches now, then go back and replace them later with ALC switches.

Finally, it *is* possible to buy Crestron equipment without installation or programming (or maybe with minimal programming). I agree with Crestron's reasons for not wanting it sold that way -- which is so that an improperly designed/installed/programmed system doesn't have a negative effect on their image. However, there are many dealer-installed systems that are also not great for their image :-)
