Best Cartridge for VPI Aries orig + JMW 10.5 ?

TWL,
In this article, Art suggest categorically but not without humour that, " low compliance cartriges are to high mass arms, what dogs are to pick-up truck", sounds like a perfect ride to me.
Because the pragmatic successfull result obtained in using his low compliance Denon 103, (refered as such by him), with the high mass Memorial cannot be discarded, I am left to favor his theorical interpretation of the low compliance c.-high mass t. a. relationship over the opposite one witch you have proposed earlier and althought this remain the conundrum that it is the fact remain that Art's personnel low compliance Denon 103 as out-done itself when partnered with high mass Memorial arm. What do you thinck of it ?

I would agree with the dog and pick up truck statement. Unfortunately, the JMW arm is not in the high-mass category. Oh, it might be high-mass compared to a Black Widow tonearm, but not in the broader sense. An arm(JMW) that is around 11 grams effective mass, is a medium mass arm. Heavy arms start around 12 grams effective mass, and higher, and the higher ones are more suitable for a very very low compliance cartridge like the DL103. I did some checking on the ideal combined mass of a DL103 and tonearm, and it comes to about 21.5 grams. Since the cartridge itself is about 8.5 grams, that would make a tonearm of about 13 grams optimal for this cartridge.

Now I don't say that a lighter arm couldn't handle it, but it would lose some of the dynamics and bass and detail in the process, from being overdriven by the cartridge.
Also, I would venture to say that since the JMW is a unipivot, it will have azimuth changes during play with this cartridge. It is unavoidable with this combination of ultra-low compliance and unipivot design. It's going to rock and roll.

I have owned and used a number of these Denon cartridges, including the DL103 and DL103R, and am very familiar with their needs, and my viewpoint is not strictly theoretical. I used them on arms that were 11 grams, and ones that were almost 12 grams, and the cartridge was clearly overdriving both of those arms. And they were gimbal-bearing type arms, which give far better stablity, and at least don't change azimuth during play. This led to my development of a tonearm mod, that was required in order to get the proper result from my use of this cartridge, with my available tonearms.

Suffice it to say that I am in disagreement with Art Dudley and his findings.

In the end, if you like what you are using, that is all that matters. I have had this discussion with many JMW owners over the past 2 years. This subject always comes up. It is very difficult for me to be as diplomatic as I'd like, and still tell the truth. I try to help, but people don't want to hear what I have to say.

i appreciate everyone's candor...that's one of the great benefits of these forums...everyone else's years of experience will help me avoid some expensive mistakes (i hope) besides, even though we are straying into denon land, as a newbie i'm still learning alot, especially as it still effects my newly acquired/yet to be set up vpi/jmw front end...still wondering helikon vs. celebration?

The two carts you are deciding on have different sonic characteristics. Depending on your preferences, warm balanced or detail retrieval, your choice would be a lot easier.

It has come to my attention that there are some new optional "outriggers" that have become available for the JMW tonearms. Apparently, this is Harry's "fix" for helping the tonearm to handle low compliance cartridges. If you are planning on using anything below 15cu, then I'd heartily recommend the purchase and use of these outriggers on the JMW tonearms.
