Csmgolf is correct. I am bi-amping my nht 2.5i's which are very power hungry. I have a carver tfm15 which seems to sound exactly the same in place of the 3490. I may just use it instead. I'm hoping to find a good 5 ch amp one day to take care of the front 3 speakers. there seems to be no 12v trigger on the 3600 and i prefer to plug directly into the wall. thanks for all the replies.
