not that the London is ruler flat, but goes out to 24 khz with realistic loads and he has some 1 khz square wave measurements...which are really interesting :)

Thanks, Dee. I wish Stereophile still conducted measurements like that.
I have the STR-112 test record and I've looked at the square wave performance of the Shure V15VxMR that I bought 10-years ago. My problem is that I don't have a high quality phono stage without RIAA equalization. I believe I used the amplifier in a two channel AC milivoltmeter to amplify the cartridge signal for the following square waves. The test record contains both laterally modulated and vertically modulated square waves on outer and inner grooves. I looked at the Shure V15VxMR with different loads.

if i had that record and wanted use it. Most likely a mic amp that can be used for ribbon microphones. Those would have the highest gain and the widest bandwidth. A used pro mic amp can be had for not much money. Also it just has to measure well :)dee

Thanks, Dee. I thought of that, but I just haven't gotten around to it. My interest in measuring phono cartridges has diminished over the years.
Best regards,

just thought i throw it in as a cheap option i have seen then as low as 30 bucks without the phantom supply.
