I already answered your question Itchesrulik in the “crisis in crisis” forum which is where you posed this question to me. But I am still awaiting your response to my question about BeHab, in that forum.
For your info. Kozov, this is absolutely not my Sevoroh. I read & studied & learned this from Sepher “Shorshei Minhag Ashkenaz” who carefully & methodically researches this involved topic. You can read this Sepher either in Hebrew or English. HoRav Hamburger shlita is probably the single biggest expert in this topic, in this day & age. There is an entire chapter in that Sepher dedicated exclusively to the authentic pronunciation of the Cholom, so that we all correctly fulfill our Chiyuv mideOrraisso of Kerias Shema & Parshas Zochor.
