I own both the Shure V15 Type IV and the M97HE. The M97HE I bought new; the V15-IV I got much later as a used item. The M97HE was a big step up from my previous cartridge and eliminated all audible distortion on my inexpensive rig. I still have 2 OEM styli for it, and I also obtained a Jico SAS. The original stylus and the SAS produce identical sound to my ears. The V15-IV had a defective original stylus, so I bought a Jico SAS for it also. The V15-IV with the SAS is the best combination I ever heard, but the M97HE with either the original stylus or the SAS is very close to it, with the V15IV having a slight edge in detail retrieval. I recommend the M97HE to anyone who asks. It is a very good cartridge.
FYI, the M97HE was listed in third place just behind the V15IV and another cartridge in a Consumer Reports test from 1982. That and the much lower price were the reasons I bought it. I'm glad I did and have never regretted it.
