without instant comparison:
I went the trouble to accurately capture my subjective experience with these speakers at length and in specific detail. I stand by my observations as written. While you are fully entitled to your subjective opinion of these speakers (and I value that information); it is a rather futile undertaking to argue my intent

Now, don't you have to go paint some walls or install some speakers?
