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!

Perhaps Tpsonic should mention he is a dealer and has an interest in the Dynavector line.
With a JMW10/Aries combo, the DV20XH was an excellent cartridge for rock and roll, actually I thought it was excellent period. Tain't heard the grado.
I replaced it with a Clearaudio Virtuoso Wood (yeck)and then a Shelter 901 and the a Lyra Helicon SL. Of the 4, the DV20 was the smart buy.
THe Grado cartidges are a little more forgiving of bad recordings than other cartridges. Little experiance with the Dynavectors. Grado Sonata is avery nice sounding cart.

Good luck!
Before buying the 20XH for my Scout I talked at length with the tech folks at VPI. According to them the performance parameters of the Dynavector add up to ideal synergy with the VPI. They could not make a stronger recommendation for matching the table. After 6 months I couldn't agree more--super sound and a great value. I'd say go for the Dyna! (P.S. I concur with the hum and vibration problems of the Grado. I had one mounted in a Rega RB300 that shimmied like crazy and my friend put one in his Aries Extended that hummed like a dog. I'm sure the Grados can sound good but I'll be damned if I could get one to run right in either set up.)
The hum deal with the Grados is an old problem; with a properly shielded tonearm cable it's a non-issue. The very expensive Dynas are very musical and sweet sounding. However the lower priced models, 10X5, 20X are somewhat lean and antiseptic sounding. They also lack the ability to provide a firm focused bottom end in a revealing system. That being said, the lower priced Grados are better at their respective price points.
