Do you have only one amp for all that gear? What other gear do you have?
The 6002 will handle one pair of 715 (1200W per speaker) or one pair of 725 (2100W per speaker) but it will not take them "to the max". The 728s needs even more power so biamp it and put the amp in dual mono, (option CH1+CH2 on the input mode, 2400W per box).
All these combos are not ideal, I would look at different amp for these speakers, even a couple of bridged 4002 would be better for the 728s (4800W per box) or the 715 (2400W per speaker), better but also not ideal.
These speakers need itech or MAi.

As I said earlier, great set of speakers but you need better amplifiers to make them rock, the difference will be amazing.
In the mean time put each 3002 bridged on each driver of the 728s (2000W per driver, 4000W per box), put the 6002 on the 725 (2100W per box). This combo will work but you have allot more in your speakers...

The advantages of the DRPA are that it has all the presets for your system components which make life easier when configuring the system. Unlike the BBE unit which uses the same values for all systems, the DRPA has different values of gain, crossover, EQ and other parameters for every speaker combo and amp it supports. It is supposed to replace the EQ and the crossover in the BBE. Use the BBE as full range before the DRPA and split the signal to subs using the DRPA. It also has feedback suppression which is very usefull.
Every amp has it's limitations, even the best, most expensive of them, the XTIs family limitation is sub duty, the 6002 is the best of the bunch for that application but still, it's no i-Tech. That being said, I also want to say the XTI family are very reliable amps, great for full range speakers and I am I the market for one as we speak.

The older i-Techs, the 8000 especially, are my favorite amps. At that system level you should also consider the headroom you have. Since the 728s is 6400W peak and the 8000 has 6000W peak per channel, it's a great fit and will sound fenominal, just don't run them continuously at more then the 1600W they were ment to be ran at continuously (this configuration has 6dB headroom). As for the newer HD series, they still have the same 6000W peak per channel so you wouldn't hear any difference due to amp power gain. They have better processing and an extra 500W continuous per channel if that matters to you. The amp section on the MAi series is the same as the one in the i-Tech.

With the iTechs it's pretty easy, you have two types of limiters, one for average power and another one for peak power. You should set the average power limiter to about 800W, depending on the music you play, no need to set the peak limiter to 120V.
These are the complete settings:
Peak limiters at 120V (attack .010sec, release 1 sec) and the RMS/Continuous limiters at 800W (attack 4 sec, release 6 sec).

Only peak limiters on the XTI so you need to trick it into doing what you want by setting the attack time to a very long time, 4-5 seconds so the peaks get through and only then, if power to the speakers continues the limiter engages.
