Yes I read that but as with all MC cartridges it depends on how it is set up, what arm/ headshell/ SUT......etc is used.
Marco had his set up spot on and it was awesome. Not heard the AT33PTGii for very long so hard to make a comparison.
I have heard a lot if MC cartridges and I would say Marcos DL-S1 was the best I have heard, probably due to fanatical attention to detail in setting it up.
