I have currently many xti amp and i want to replace them by itech. I run a vrx pa on them. I want to use the process inside because i dont want to buy a driverack or a xta. The itech are at good price but ive heard they are not that much realiable. Any one knows if the hd are more reliable? Those new itech hd sound better(i have been said) and they got the bss process inside and levelmax. + cobranet seem to me to be a advantage and the new v5 preset. My question is, is it really worth paying 1000$ per amp to get those new itech hd.
