But according to most the Delta's are too loud. I love my Delta 13 Elite. If you don't throw the balls in the rack and then slam it back and forth 25 times they really are not that loud.
Get some leather inserts. It makes a very big difference and looks cool too. The inserts absorb some the the vibration that resonates into a metallic sound. It truly does soften the rack noise and you can rack away without any sound discomfort.
