VPI Scout with Grado Master - but what next?

I've got an old original VPI Scout with a wood body Grado Master HO MM cartridge on it. I'm using the phono stage in my McIntosh C2200 tube preamp, and pushing the whole thing with a McIntosh MC402 solid state amp. I listen to Jazz mostly.

The Grado Master is about eight years old now, so I'm starting to shop around for a replacement. I had a Grado Sonata in it originally but it was pretty thin and boring sounding and didn't track very well - the Master has been a really wonderful cartridge. However it's a lot better with Jazz than it is with Rock. Rock, even excellent 1/2 speed master recordings, sound forward and lack slam.

So I'd like my Rock to...well rock, but jazz is my main thing, and I'm worried that if I buy a Dynavector or Soundsmith based on recommendations from folks who listen to Rock exclusively, I'll wind up with my Steely Dan bringing down the house, but Leroy Vinnegar sounding like Jack Bruce and a stack of Marshalls. This would be bad. Anyone

I'm using a Target PS-1 wall mount shelf and replaced the MDF support platform with a Symposium Svelt Shelf. They make one that is an exact fit so it drops right in. I never A-B'd the Svelt shelf against the MDF but I'm thinking it provides better isolation. In my experience, the main thing is getting the table attached to the wall studs rather than connected to the floor, regardless of what kind of support you use.

Regarding your query on cart. output: I use the Master now and have had a lower output HOMC Dynavector in the past. Never noticed any difference at all in the perceived volume, presentation, or noise levels. You would think cutting the output in half would make a big difference, but that doesn't seem to happen. Of course, YMMV depending on preamp. I am usine either the George Wright 200C or the Cary SLP 90.

Hifiharv, I noticed your remarks about gain differences between the Dynavector and the Master not seeming to translate into noticeable differnces. I found the stated gain of .5mv for the Grado Master to be very optimistic, at least when compared to the gain of similar rated outputs from Ortofon cartridges. The .5mv Ortofons seem to put out twice the voltage of the Grado even though they're rated the same.

Photon, maybe that's why I hear no difference! Wouldn't surprise me that a manufacturer would exagerate the output specs. Wonder if LOMC makers do it as well? Did you actually measure this yourself? What does one play to do so? So there is no confusion to others reading this, I would like to point out that the Master is claimed to be 5.0mv rather than .5mv. .5 would be half a millivolt. To elaborate, I don't remember the claimed output of all of these carts. but I recall some being 2 or 2.5 mv. I have used them all in the same (tube pre)systems and heard no perceived problems related to their output: Shure V15 type V mrle, Sumiko Bluepoint Special, Shure Ultra 500, Grado Master, Grado Reference, Dynavector 10X4 Gold (rare, factory hot rod of the 10X4), Audio technica AT150MLX. These may not vary that much in output now since I was assuming the Grado's were the 5.0 they claim to be.

Oops, my bad. I forgot the fact that Lemoco was discussing the 5.0mv HO Grado. My Statement Master1 is the .5mv. model. My previous Sonata was a HO 5.0mv. model and I don't remember there being such a disparity between its output and other 5.0 mv cartridges I own. As to how I measured or determined the output of cartridges in my system, it's just a matter of familiarity with a given lp and where I set my volume control. When I'd switch from the Grado to an Ortofon rated the same output, I'd have to always lower the gain setting on my RCM Sensor phono preamp to maintain the same volume settings on my line stage preamp. I tried experimenting with resistance as well to see if that was a factor, but the Grado is relatively insensitive to loading in my experience. Even the Grado factory says not to worry too much if you have use a lower resistance than the 47k. specified.
