I bought the Excalibur Matrix 380 two years ago, and it is bad "bootie." I like the fact that I can change the string and be back in the hunt, if need be, in a matter of minutes. Strings are inexpensive compared to a compound CB. If you really want a compound, look at the Mission line, as you do not need a press to change the string/cables.
I will say the Matrix 380 is not your typical "lets go out and shoot a bunch" because it can be a bear to [censored] and shoot if you have a bad shoulder. But, they do make other Matrix bows that are less poundage. If you really want the top of the line compound, Ten Point can't be beat.
Now, as with anything, you get what you pay for at times, and I'm not bashing any one crossbow, but since you mentioned budget doesn't matter, or something to that effect, I threw out the top of the line.
I will say also that all bows, no matter what they are, will make noise, but I was really surprised that my Matrix 380 was quite.
