I agree that Heavier the arrow Quiet a bow down However if you shoot bows side-by-side with the same weight arrow you can and will hear difference in how quiet a bow is. No way are they all the same
I think it will depend on how the bow is set up...arrow weight, rest, stabilizer, etc. That being said, some will be quieter out of the box than others with nothing but a whisker bisket on it but even then it can be somewhat subjective. Bottom line, you'll have to shoot several bows set up as close to the same and see what you like.
I have an obsession evolution and it is extremely quiet. I also shot some mathews bows that were quiet. Like posted before it depends on the setup. I am very happy with my obsession.
I thought my Carbon Spyder 34 was quiet until I shot an Xpedition Xcentric......that thing will amaze you!
I'm with pastorjim my Elite 35 is very quiet and next in line would be an obsession. On the other hand my roommates carbon knight seemed creaky and noisy when I shot it.
My Creed is really quiet. It is the quietest Mathews I have owned. I think the No Cam HTR I just ordered may be even quieter.
I have both a PSE Bowmaddness and aMatuews Heli-m. Both bows are very quiet, quiet enough for me anyway.
