Do people think the 3801 with it's extra amp channels is a better bet than the sr8000? (using 50/50 ht & music). Is the ex, es thing just a selling gimmick or is it here to stay? In Australia we seem to miss out on DVD's encoded with the extra channels - so far (we don't even get much in the way of DTS titles at this stage). I am concerned that Denon have packed in the extra amps at the expense of sound quality (can it really do 100w x 7???). Is 7.1 so much better than 5.1 ?
