I've had the Crest CA-9 now for a couple of months, and while I am very happy with the sound, I am very unhappy with the weight and size. The thing just feels heavier every time I pick it up. I have the CA-9 racked in a 2 space anvil style case, and it weighs close to 75lbs. I'm trying to talk myself into keeping the CA-9 based on tone alone, but it is soooooooo heavy. The new PLX2 series PLX2502 only weighs 21lbs, can fit in a gator shallow rack, and has a lot more options. But, and this is a big one, does it sound near as good as the CA-9? I've often thought about getting a Stewart 2.1, but am not crazy about the reviews I've read about them. QSC seems to have a great reputation here, but can it take on the mighty CA-9 for bass reproduction? I like using a power amp with my UL502 and UL410 on the gig, as it really seems to get me to push the UL410 a little more to get a fuller response and more punch. While the UL502 works great alone, I do find the CA-9 adds that little bit of girth I was missing. Will the PLX2502 cover that for me?
