What Cart. for a Infinity Black widow

Johnnantais, you could well be right. I've been using the Grado Reference/Reference (love their nomenclature) in a JMW l0.5 arm -- often a recommended pairing -- and experiencing both poor warp tracking and the dreaded Grado wobble. Worse, the Grado was soundly defeated, soundwise, in this setup by the Shure V15xMR, which surprised the hell out of me.

Dopogue, If you have the means - and your JMW tonearm suggests you do - then I urge you to buy a Morch tonearm, which can be ordered with a variety of arm-wands of different masses: a crucial issue (or you can do like me and buy a variety of old and new classics). The Grado is truly a world-class cartridge, even the Platinum is awesome, given tubes and a low-mass tonearm. As to your Shure, I believe that overall, taking into consideration things of musical importance (tonality, timing in the more complex sense of retrieving the rhythmic interplay between instruments: the heart of the music), the Shure may be the best cartridge in the world. Of course, given the ridiculous prices of "high-end" (and musically flat) equipment, only the rare reviewer has the courage to say so, but it does get said. I notice you mention only MM cartridges. I notice that again in terms of the more complex timing issues, MMs are superior to MCs overall, but I don't know why. But since almost nobody is producing low-mass tonearms (the cowards), not many people get to hear them like they should. If you get the Morch, then you can hear both the Shure and the Grado as they should be heard (which will require two arm-wands), though in terms of mass-matching, and from your experience, the VPI is a good match for the Shure. I confess I am a vinyl junkie, I just love watching those platters spin around. And more and more, MCs simply bore me. Now I've done it, they're going to crucify me!

Johnnantais, Thank you for your thorough review of experience with the Shure, and Grado. Although my own view that these are reasonably priced, quality reproducers is from use on the Rega RB-300 with the Kerry F-2 Titanium Heavyweight Counterweight, I am now aware of even better results possible with your low-mass tonearm recommendation.
Since the Grado already sounds so terrific, I guess I will just get more confirmed in my opinion that vinyl pleasure does not always require spending more and more, but learning how to use what you've got.

I sell the Shure cartridge and own a V15 and it is a fine cartridge but, it sounds mechanical compared to the old Carnegie moving coil that I use for most of my listening.

I was just thinking about the Denon HO MC's DL-110 & the DL-160 they are very light 4.8 g's and the grados are 6 g's. Wonder how these would sound compared to the grado woods?
