Great bass from a linear tracking arm?

I think my nude brinkmann emt is quite light and that was the cartridge I heard on the AT - it has no body after all. I am guessing it is 6g? What does the zyx universe weigh?

The Brinkmann EMT Titanium phono cartridge is 11 grams.
Maybe the one you were using was quite different than this?

The ZYX Airy 2 and Airy 3 are each 5.0 grams. I believe the Universe is either 5.0 or 5.5 grams.

The UNIverse I have has the SB, I think, it is around 9 gr. A friend uses a Zyx 100 in his Air Line and he told me, it is very good (he owns a UNIverse, too), also a Transfiguration.
I think, weight is one point, but probably the siffness from the needle bearing the other. I saw a few pics with the airline, fitted with Benz LP, Kuzma Cartr., Transfiguration, Lyra Titan etc. So I guess, weight alone is not the secrtet.

I just talked to Mr. Kuzma at CES and he is just now offering the ZYX cartridge line under his own name, without any changes to the cartridges or the prices.

Nope, I was just guessing as it doesnt have a body. It might well weigh a lot more. However I am using the older emt - not the titanium (which replaces some plastic parts with metal) so the titanium could be heavier. Is the zyx really half the weight of the emt?

EMT compliance is 15 micro m/mN

The AT bass was still pretty good - on a par with or better than many pivoted tonearms but nowhere near as good as the brinkmann arm. I would certainly revisit the AT with a higher pressur epump to see what effect that had.
