Did I do a good thing or not?

If you prefer the Shure to the Acutex, I’d be surprised. But I’m interested to know.

After Saturday is when I'll know. That's when the new stylus arrives, so Saturday will be ike Christmans around here!

Give it a week or at least several hours of listening before you make a judgement. All new audio gear is a rose at first and then after long hours of listening, sometimes the bloom is lost.

Which arm do you wear your Rolex on?

Of all the MM cartridges I have, I love the SHURE V-15 VMR the best. Before becoming mostly a MC man, I got a JICO SAS stylus for it. Not sure if you can still get them, but the last time I looked they had become stupid expensive. I think JICO has some other MR upgrades available. The SAS was definitely an eye opener and I stuck with that as my number one for many years.I never heard the V-15 IV, but read that it was a little bit of a step down from the III, so I think your going to love the V-15 VMR.

Disclaimer: the first good cartridge I evet had was a V-15 III MANY years ago, so my ears may have been preconditioned.

All the best, Jim
