HELP! -Top Best quality stethoscope for the doctor?

My husband is debating who should do it in one doctor stethoscope PACES prepares to take his two weeks (which is particularly attentive to the whispers minutes, even), and in order to improve the quality of stethoscope you can get. Of course, you have a stethoscope (Sprague model-based), which is fine, but not much. He did not listen to the best of my Littman II SE, and is not impressed with the Littman Master Cardiology (which is what most of his colleagues use.) She loves Littman 3000, mainly because it can increase the volume and concentrate on the sound, but the problem is that the supervisors review the use of electronic stethoscopes a bit difficult. Suggestions? Cost is not really an option (well, unless they exceed U.S. $ 500) because we want the best quality. Any advice is welcome. Apparently, you have to be able to hear diastolic murmurs grade II, such as multiple sclerosis subtle, AR, and differentiate MR, VSD, HOCM and TR.

I am very surprised that he is not satisfied with the Littman Master Cardiology .. I heard he's better this case. Well, anyway, go to 3M and can compare different Littman stethoscopes. In my opinion, Littman always the best ..
