As the title says I've got a quiver with 169 Dex & a 46 dex gem & +10 Max Disc. Means that the quiver can go up to 227 dex with 15% IAS (The highest possible on a quiver). This quiver has the most dexterity you can possibly get with a socket & +10 Max Disc. Offers can be in gold or RM!
Edit: The gem is worth about 700k too so keep that in mind
