hey nice to heard that someone agrees with me that the ada 885 not bad, so i see you also brought a dell thx series with the turtle beach santa cruz card? i brought the ultras and still use the ada885 too by having the ultras on my dd5.1 and sending the ada885 through analog rear. for some reason when sending digital mode in the turtle beach santa cruz card, the rear is still analog? maybe that how quad setting worked for me on the ada885 when i used digital cause i hooked both digital and analog cables on the ada 885. But oh well i can use the 4 subs i have now for max sound. lol to count ultra sub, sws, ada 885 sub, and boston acoustic 7500 on ac3 of the digital out while the ultra on pcm out from my sound card
