Andis and Oster clipper blades are interchangeable as you know.Personally l prefer the Oster gold a-5 but that is a personal choice depending on how many dogs you are grooming and if they are pups.l hate the Wahl as they are noisy and cannot be repaired properly and the Andis are used by many groomers especially the Ultra edge 2 speed although to tell you the truth l am not over fond of two speed at all.if you contact Andis and talk to them re noise levels they are more skilled hen anyone here unless a professional groomer.You aLuckyky if in the States as it sound like you are as you can get far cheaper products than us in my country as our power voltage is different so they have to be nade for our country and cannot be bought dirrectly from oster or Andis.If you have a good person servicing your clippers he is the best person to ask ashe knows all brands and is competent to give a good answer.When l do pups l use a small Oster red domestic clipper,very very quiet but no longer avail as pups freak out with noise.l am not a preofessional groomer but do groom many dogs l have sold plus my own for shows and they are onlclippeded in certain areas.Out of interest try one of the top andis blades ans see if that helps.the other thing l find is when l have the radio on full blast the dogs do not seem to react to the noise of clippers as much.
