Thinking about buying a Bowtech assassin. Would like to here what y'all think about them.

fast as all get out and loud as hell. i killed 4 deer with mine and 2 were spine shots due to a jumped string. and one i shot at 45 yards actually jumped the string and spun before the arrow got there. she was broadside when i released and the arrow went in her hindquarter, broke the femur, severed the femoral artery, and exited right under the spine in about the middle of the ribcage. i will be hunting with a mathews creed this year.

As stated above, fast and loud. I also believe it is a bit jumpy at full draw(that is probably more user error though). That being said, I still like the bow and will continue to use it for a few more years.

Any suggestion on making them less noisey?

sell it and get something else, that is what me and all my friends that had them except one have done. my last friend that owns an assassin is on the verge of selling it.
