I have been using both the Takatsuki and the new WE 300B. No experience with the Elrog. However, I am only using them on my mid-range. Both the Tak and the WE are very quiet, but the WE a bit quieter (my midrange has 112dB sensitivity, connected directly to the amps). Talking to Charles Whitener, he said WE has a patented method of hanging the filaments that results in low noise. I feel the Tak is a bit more laid back and more "rounded", and the WE sounds more dynamic, but again only by degrees. Both are excellent. I have used the Taks for about 3 years before putting the WE in about 3 years ago. I put the Taks in again last month just to see if there is a difference, which is very slight. I can't say which one I prefer.
