Well, I did it. I ordered a Crown XLS 1502 from Amazon today. It won't be here until around May 8th. This will be the first time for Class D in my system and I am very curious to see how it compares to my other amps. Obviously, at its low price I am not going to make a global judgement about all Class D amplifiers based on the way this one sounds.
My main motive is to see what it does for lower efficiency speakers that like power, and of course its overall sound quality. I will report my findings once I have given it a fair try.
