Hi alan, Regarding the AR9 speakers that I used in my test for sibilance,they are not the vintage AR9's.They are one of the last speakers AR produced before going defunct a year ago.Their published frequency response is 32hz-22khz +-2db's.Listening to them I find that they are not as detailed (bright) as the m80's but they are certainly not lacking in highs.I to used to own the AR2ax speakers so I understand where your coming from , however the AR9 is a different breed.
