I just took the gain difference in account an made it up in the bandpass gain of the crossover. It is just not worth 3 times the cost and several more pounds to me to have the amps match. The XTi does great on the highs and is the last amp in my rig I have to watch when pushing the system.

What everyone is forgetting is that different DSP amps have different latencies that need to be compensated for in the phase alignment of the crossover. I don't think the XTi latency is published but the Itech is.
In comparison to the feature set of an Itech, the XTis appear to be a heap of garbage, and usually sound like it too...
And if you use a DSP amp with an external DSP then you're missing the point. With possibly the exception of using the AES digital inputs on the Itechs to avoid the extra AD/DA conversion.

Johnny scrimped and saved for 2 years to buy his first XTI. He's been longing for an ITECH but just can't get the cash together. He's so proud of his first purchase that he made a new account on PSW to talk with real people about his amp. Then he saw Silas post telling him that his new purchase is garbage. Four years back in therapy for Johnny.
When one has a point they're trying to get across, they sound more intelligent if they don't bash things.

Maybe I was getting a bit grumpy after being awake for 25 hours at a really tough gig
Anyhow, XTis have their place, but running them with Itechs really is a bad idea due to the delay problems.
Also, if you compare the
feature set of the two amps, it will in fact seem like the XTi is severely lacking, just like I said as my grumpy self.
I am always extremely surprised at the number of people that buy DSP amps and then run them with their external DSP anyway. I'm not saying that anyone in this thread is doing it, but don't these people realize that they are experiencing a severe sound quality hit when they do this?
And, I don't see the problem using Itechs to power HF drivers at all. I routinely biamp cabinets with one Itech per, and it makes lots of sense. XTis don't have the capability to be deployed and managed in any sort of large numbers (like more than 1 rack full) because they don't have Ethernet.
Also consider that your 75 watt HF driver may be able to withstand a 500 watt peak with no issue--there usually isn't an excursion problem like with woofers because of the higher frequency.
I think it was Sound Image that uses Itech 8000s on everything, even the HF in their wedges.
I'll try to be happier after getting my 23 hours of sleep
