I'm not familiar with the Dominet, although ADS is typically a "high-quality" brand. However, for that amount of money you could buy a Crestron multi-room audio system, which would be much more versatile. $6000 would buy you a CNX-PAD8 multi-zone pre-amp, four CNWP12F single-gang "transport/source" keypads, four CNWP12N single-gang numeric keypads, an ST-CP controller, and leave $1000 to $1200 for an amplifier (probably Niles or Xantech).

Since the Crestron is "logic-based", it can be programmed to accomodate numerous functions that are not possible with other systems.

For example, minimum and maximum volume levels can not only be pre-defined, but they can be altered by other system events in "real time" -- ie, Zone 1 (kids' room) has a maximum volume of 80% during the day, 50% after 7 pm, and 0% after 9 pm. Or, Zone 1 can never exceed Zone 2, etc.

The buttons on the keypad aren't "locked" into any particular function either. With most other systems, if you had four satellite receivers (or CD players, FM tuners, etc), you'd need to have *four* SAT buttons -- Sat 1, Sat 2, etc. With Crestron, you could use *only one* SAT button, programmed to select the first receiver with one press, the second receiver with two presses, and so on. And the Sat button's LED will blink a corresponding number, to confirm the selection. You could even set it up so that a single press *automatically* selects the first available (not currently in use) receiver, from a pool of however many.

With the numeric keypads, entering a value greater than 100 selects the satellite channel as you would normally expect, however entering a value *below* 100, such as 1 through 0, will recall one of the *preset* stations. Pressing and holding 1 through 0 will store the present channel to the corresponding preset. This same logic can be applied to radio tuners, CD changers, and hard-disc "jukeboxes" (groups, playlists, etc).

Since you'd already have the Crestron controller, it would facilitate integrating other subsystems in the home. The ST-CP has two serial ports, four IR ports, and a built-in RF receiver (for wireless touchscreens and remotes). You can also add up to 255 I/O expansion devices or hardwired touchscreens.

And that's just the "tip of the iceberg" :-)
