G'day all, I've not visited this site for a long time. Firstly, I am truly shocked to hear of John's 'TheChairGuy' passing. A very sad loss.
Regarding the Shure M97xE I've changed my mind about 62 k loading. Whilst loading at 62 k does improve the upper treble, it does have one unfortunate and I consider unacceptable negative in that a very audible midrange droop results. I've since realised that perhaps the best attribute of the M97xE is its midrange response when optimally loaded.
I've conducted many, many experiments and listening observations in recent times and I and one or two others, have gone back to 47 k loading but the optimum capacitance loading is somewhat critical with the Shure M97xE. Shure 'officially' recommends 200 to 300 picofarads 'overall', but I think that range is too broad. I think 250 to 300 picofarads is best. My set up in here measures 47 k and about 270 picofarads 'overall' (from all sources... tonearm wiring, interconnects and phono stage input capacitance itself), and I couldn't be happier.
At that loading the Shure M97xE has a very musically satisfying and endearing sound. I love it. 47 k and 250 to 300 picofarads load capacitance 'overall'. Regards, Felix.
