RedSIinPA, I'm glad you like classical music but if you think of it as "soothing" I suggest a few ear openers: Orff's "Carmina Burana"; the last 2 movements of Berlioz's "Symphonie Fantastique"; the opening of the last movement of Beethoven's Ninth; any symphony by Gustav Mahler except maybe the Fourth (his music has the best claim to the word "titanic" of any I know); and of course Stravinsky's "Rite of Spring", particularly the last section. Any of those ought to wake your ears up, biiig time. They're also tougher tests than ANY other type of material for the quality level, as well as power, of the whole reproducing chain.
I'm sure lots of you all reading this could name hundreds of others, no problem.
