hooked it up today.

very clear and dynamic. I didnt change anything and am listening to the same stuff I always do and it sounds very detailed.

this is as good as the original as far as sound. will it last 15yrs ? dont know. does it sound very good? yes. it does

anyone who says the new is not as good as the old hasnt heard the new. I have , I have had the old many times. this is every bit as good and clean as the old. much clearer than the Boston Acoustic I had before in the same install. this is crystal clear.

very dynamic and the left /right channel seperation is great. I am hearing stuff I havnt heard quite the same before. detailed.
