Dynavector or Grado ?


I plan on purchasing the VPI Superscoutmaster and prefer to have the cartridge mounted by VPI before it is shipped to the dealer.
VPI will mount Dynavector and Grado cartridges ONLY as they are the 2 brands they sell.
Query...which is the better sounding cartridge?
The high end Dynavector lists for $4000 and the high end Grado lists for $2500.
I only listen to rock and roll music.
For reference, I have an Arcam FMJ pre amp. with a phonostage and Arcam FMJ mono amps.
Thanks for looking!

Theaquaman.how do you feel about myposting on your forum topic,would it change your impressions of what I said?
It's not up to aquaman to decide this. I have no personal grudge against you sir and you have not attacked me in any way. My position is any dealer posting on any topic should disclose the fact that he/she is in the business. It simply eliminates all semblance of impropriety and/or conflicts of issues. I do, however, respect the information you offer.
Dear Tpsonic:
Theaquaman welcomes ALL opinions! No, it doesn't change my impressions.
I have listened to VINYL for almost 30 years and for the past 23 years it has been on my beloved Harmon/Kardon T60...so, I appreciate everything that is posted.
By the way, my local dealer sold me a Grado Platinum for my T60 just last year to replace a ShureV15 which I bought at the same time I bought the T60. So, I have some experience with the wooden Grados already. I like mine.
By the way, thanks to all members who have responded to my question.
Stanhifi/Theaquaman.Thank you.I believe it was time to let the light of day shine in and illuminate things in full view.I understand now.Must I make this disclosure -everytime??I don't sell much of Lloyds' gear in the course of a year and I do try to stay clear of topics directly related to products I sell(Walker/Silent Source/Omega Mikro).Stanhifi-Sorry for the Purist digital cable entry-thought it was a different way to skin-a-cat,no offense to anyones' kitty.
Aquaman, just a few follow-up thoughts:

1. The on-line owner's manual for the Arcam FMJ two-channel stereo preamp indicates that the MC phono stage is designed to accommodate "low output cartridges." That is a good sign. If you have any doubts about your phono stage having sufficient gain for some of these low output MCs, it is probably worth a call to your Arcam dealer to inquire about the gain of the Arcam phono stage module.

2. Based on personal experience, I can vouch for the exceptionally linear frequency response of the Dynavector XV-1s cartridge. It is not bright and forward sounding. It is also not lean in the bass frequencies. The cartridge is as extended at the frequency extremes as any I have heard, and the frequency response of the cartridge sounds dead neutral to me. I don't have any experience with the cartridges further down the Dynavector line, so I can't offer any comment on those.

3. If you choose to go with one of the Dynavector cartridges below the XV-1s, you will find that some of those cartridges are just a tad bit light in weight to make for an absolutely perfect match with the JMW-9 tonearm. Assuming I am right about that tonearm having an effective mass of 11g, you will find that most of those cartridges would probably benefit from the use of one of VPI's 3g stainless steel cartridge weights. They are specifically designed to allow the VPI tonearms to pair more ideally with light low compliance cartridges such as the Dynavector Te Kaitora Rua or the XX-2, for example. VPI's web site indicates that the cost of one of these 3g weights is $15 retail.
