Interesting reading Andy. How is the M44-7 coming along and what are you initial impressions vs M55E.
My own take on the M44-7 range of cartridges was that they paint a broad big bold picture where as the V15, M55E, M72, M75, M91 were a bit more subtle and orientated at audio enthusiasts. I think it may be true to say the M44-7 was a DJ cartridge with a sound to match?
I feel if I were to continue my exploration of the Shure cartridges I would once again dive into the SAS pool and come up with another Frankencartridge based on the M55E which would be another old vs modern hybrid?
