How good was/is the ZETA arm

I used a Zeta with a Michell Gyrodec and a Denon MC with transformer.
Sound was super.
I would rate it as good as SME arm with such cartridges.
Zeta is strictly a medium to low-mass tonearm. It became popular after Sumiko stopped making The Arm and started jacking up the Shure prices.
If you are a MC fan and track around 2 grams, I would say it is hard to beat a Zeta.
