Things I do to silence any bow I own:

I take off all accessories and then put a layer of moleskin anywhere that metal touches metal. Then I put the accessory back on. This will reduce vibration traveling from the riser to the accessory, or from accessory to accessory. I also never have a quiver on the bow. They are simply too noisy for me. I also never shoot a drop a way rest. Moving parts make noise. For me, the wisker biscuit is hard to beat for silence.

I try a few different stabilizers. Each bow seems to be affected differently by different stabilizers. A good one pays dividends.

In additon to the typical limb savers, I put a cable dampener on the cable guard. They do work.

I make my strings two strands larger than normal. A heavier, thicker string will silence things quite a bit. To this I add cat wiskers to the string and the cables.

Shoot a heavier arrow. Mine are around 530 grains out of a 65 lb draw weight. This will work wonders, not only for the silencing effect, but will give you a heck of lot better penetration.

I tied a Catfish Loop on my string. These loops fit loose and for some reason they have a vibration reducing effect on the string. This causes only a small difference, but I'm one of those guys who do lots of little things to reduce noise. It adds up to a lot in the end.

In addition, I make sure my limb pockets and axels are well lubricated. Grease not only prevents squeeks, but it has a bit of a dampening effect.

It seems like I'm always shooting the most quiet bow at my local range and it doesn't matter what brand the other guys are using, or the brand I'm using for that matter.
