Ok finally got a chance to catch up on all the replys to my post here. Thanks to everyone for all the input. Seems as if I do have "upgradeitis". Do they make any creams or anything for that? It just wont go away! I dont really want to change the W's that I have as i like the look and expect they are of the highest quality for on wall. I have just upgraded from QS4 to QS8 and from the EP175 to the 350. I hope to get better performance due to those changes. I am however surprised to hear that most say an amp wont make enough difference. I know when i have added amps to car audio systems in the past the difference was enormous. I assumed it would be the same here.
