Decca London Gold cartridge nightmare

Having read so much about the Decca London Gold cartridge, I decided to try one. Time passed and I finally found one on ebay that was within my budget. Cartridge was guaranteed to work with good results by a seller with very good feedback. Physically the cart looked neat, and everything, except for the mounting screws, was intact.

I had intended to install the cartridge in a new Kuzma Stogi S arm on a LP12 turntable but since the arm is scheduled to arrive end Oct 2008, I decided to try the Decca on my Lenco L75, with the original Lenco arm. At least to make sure all connections were OK, if not for any other reason.

What happened afterwards was pure nightmare. The results were horrendous, to say the least!

Tell me where I went wrong.

I tried tracking between 1.5 to 3gm but the sound ranged from tinny to severe breaking up. Even more startling, the groove vibrations picked up by the stylus was transmitted to the entire headshell, so you could actually hear the sound of the grooves generated acoustically by the vibration, kind of like a diaphragm or a gramophone horn. Lightly placing my finger on the headshell while a record played confirmed this. The headshell was quaking! With the preamp gain down to zero, you could hear the headshell vibration from a distance of a foot and a half, maybe even further, I kid you not.

The cartridge that I am presently using on my Lenco is a low output Audio Technica MC, the AT-OC3. No problems there. Tracks pretty well too, but not great, considering the Lenco arm was not made for MC carts. But the results were definitely more sane than the Decca!!

What's happening? Help!

Thanks for any advice, suggestions, feedback.

Just to echo the previous responses, the decca responds most postively to unipivot damped arms. I've been using decca cartridges for the last 20+ years and have become very familiar with all of the little nuances associated
with this cartridge. I'm currently using the supergold with a Keith Monks tonearm which was designed specifically for the decca. Decca's usually track best around 2 grams.
Well tempered arms have been known to work well with this cartridge.

Dubhouse, I have not done any mods as of yet, however I have thought about it but you have to be careful about those kinds of things as the decca's can be notorius for hum if things are not done just right. My philosophy is if ain't broke don't fix it.
The Linn-Lp 12,keith monks and decca gold was a marriage made in heaven and as mentioned before, the keith monks was designed specifically for that marriage an after 20 yrs. of that marriage and this so called old technology, I still haven't heard anything sound much better and yes I've heard other systems. In fact my very good friend and audiophile buddy just came back home to decca after a short hiatus with some other cartridges(clear audio maestro)to name one because he just couldn't get that magical sound the decca has. He's using his in a sme v tonearm and truthfully it doesn't sound that much better than my setup and his sounds very good! Its just something magical about the Lp-12 keith monks decca combination, I can't explain it.
Just to let you know, I have the M9ba mkIII version and it sounds better than the decca international arm.

Teeny increments? I wouldn't recommend ever pulling the stylus tip on a decca backwards. That's asking for trouble.
If you look at the construction, you can see that its very delicate(flimsy) at best. Any attempt at adjusting, unless you are a qualified technician(of decca's)would be disastrous. IMHO

Tbg, I still have a working Keith Monks mounted on a Linn LP-12 valhalla with a Decca supergold. I've been using this combination for over 20yrs. and still haven't anything found anything that I like better. The Keith Monks was designed for the decca and is a marriage made in heaven.
