SA,
Aye, we will have to agree to disagree. I do not dis-value a quiet bow, I just believe it's not the biggest part of the equation.
Any of the Mathews Q series bows should fit your bill. If performance is not a concern then you might also look into the Pearson/McPherson lines. Very smooth, and they make my Q2 sound like a gun.
The new Hoyt's w/ Excel cams are very quiet too, an UltraTec or Pro-tec should fit the bill.
PSE's new Enforcer suprised me as well.
