Grado Reference vs Benz Glider and H2

I am using the Morch UP-4 Arm with my Grado REF.and used the Cardas test record and was shaking really bad at the 10 Hz signal,But not at the 8 hz or above the 10Hz .I am using the red dot version for the arm,But have not encountered any problems except when I have a somewhat warped LP things can get very bothersome,extreme concave
and things get very bad indeed.Luckly most my LP's used or new are flat and in nice condition.

Hi Doublebass;

I get subsonics on every record with the Rega arm. Apparently the Grados excel with low mass arms how do you like your Grado Ref/Moerch combination?

I've also been looking at the Haddock but don't know if its suited for a suspended deck.

Overall the Morch Up-4 with my Grado is a very magical experience indeed.I also use the Wally Tracker Protracter mirror to get that last bit of retrival off the LP grooves.
It is sensitive too VTA changes,and I try not to fiddle with it to much.I know when its right on,the highs extend way out with incredible ambient retreival and the bass gets deep and powerful.The magical midrange stays the same irregardless of what VTA setting I use.
I would reccommend this arm if you can find one used.The arm wands are interchangable which is nice.I hear some people prefer a slightly higher mass version of this arm,But I have not had any problems with mine at all except on badly warped LP's.

i have an H2 on a vpi scout and love it.

For me, the Benz cartridges occupy the middle ground between the fast, highly delineated sound of the uber moving coils favored by most audiophiles, and the rich, smooth textured sound offered by the Grados, Shure V15s, etc. In addition, the Benz cartridges from the wood bodies on up do something special with tonal balance that favors vocal, woodwind, and massed string reproduction in particular. Like the Grados, I find the Benz H2 to be a natural, rather than supernatural sounding cartridge. However, unlike the Grado Ref it is more rhythmically lithe, which shows up particularly well in bass and percussion heavy recordings.

Unfortunately, I can not comment on the suitability of either the Benz H2 or Grado Reference with your arm and table. That is what a trusted dealer is for.
