I hope you didn’t think from my posts that I was denigrating the MC 201 or the 40 Ohm version of the AI SUT as that wasn’t my intention. I think it was clear that I have not experienced the MC 201 through the AI SUT so I cannot even comment on that combo, let alone state it is lousy. I can only report a disappointment I had in the MC 201 when using an Audio Technica SUT some years ago and also a disappointment i had in using the FR1 with a 40 Ohm tap on an SUT. I think mjw21a has something with the whole tonearm mass thing. I am using the MC 202 with a tonearm which has an effective mass of 21g, including headshell but excluding cartridge weight. I think what we need is for mjw21a to give the FR1 and MC 201 a test drive through the 3 Ohm tap of his FRT4 and report his findings.
