So my speakers are going to be here on monday which I am so excited about. I have just one more question. Would an onkyo integra dtr 9.9 be overkill for the epic grand master 500 speakers? My onkyo rep said it is underated at 145w/channel. I have the ability to purchase direct from onkyo at 20% below dealer cost so I can get it for an excellent price. Just wondering if it is worth it?
