Dear Twl: This is not a fight. The issue here is only: low compliance cartridges with an unipivot tonearms:
I have some experience with unipivot tonearms ( I own five of these ) and I try with low compliance cartridges: Denon, Shelter, Koetsu, Victor,.. .... ( that I own too ) and I never have any problem with this combo-combination: " no rock and roll " ( like you say ). I think that the problem is in the design an execution of that design. The Graham is not an original design ( is a bad copy of the Audiocraft tonearm.), tha's why to much up-grades every " month " and the JMW is not, too, Mr. Weisfeld take some things from the Audiocraft and SAEC tonearms ( he speak about this in the early times of his tonearm ). So if anyone has problems with a cartridge in those tonearms is because the tonearms have problems and not because they are unipivot tonearms. Twl, the theory about it not always is true in the real world because there are many parameters out of control.
Till today, many of the best unipivot tonearms are of Japanese design ( the Morch is a very good copy of the Japanese Highphonic tonearm ). In the time where the Dl 103 or the Black Koetsu born the unipivot tonearm ( like the tubes ) has a very strong force between the Japanese audiophiles and that people live " happy " with those combos ( I have some japanese music-lover friends that still lives in Japan ) still today. So, the problem is not the unipivot way. Now, if you like or not the sound of a low compliance cartridge in an unipivot tonearm, this is another issue and has many " roads " to talk about it.
The other issue is compliance in front of tonearm mass, but this one in some other time.
Best regards and always enjoy the music, not your audio system.
Raul.
