BMS 4592ND Mid vs 4592-16HE Mid Shorting ring question in Technical/Modifications Posted August 18, 2019 Glens, Thanks for the input. Shorting rings are added to lower distortion and (I believe) flatten impedance, but I can't say if these are helpful at my listening room levels. That is the information that I am seeking. I think that I am fine to buy standard model, that is for sure, but it is worth my while to seek some insight from anyone who has compared them... if such a person exists and is on this forum. I used my current EV1824M for over 30 years, I would like to repeat that success of selecting, buying, and then stop thinking about it. While I'm at it though, I should show diligence.
