Best cartridge for SME 5 Tonearm?

Yes absolutely, I know that the V and SMW12 will work very differently with different cartridges based on the length. I need the best mechanically working cartridge for the SMEV and only then, after I can make choice on the preference. Thanks for that point.

The Benz LPS or the Benz Ruby make a good pairing with the SME V arm. A few here, including myself have used that combination with success

Anyone any experience with Dynavector XX-2 Cartridge. I was told that this combination is stunning by and SME Guru.

...I was told that Ortofo (I am currently using the Ortofon) are not the best matches for this arm due to the design,....

Absolutely not. Ortofon cartridges are a superb match with the SME tapered magnesium arms. The Cadenza series, a NOS Jubilee and the stunning Windfeld are all perfect on the SME arms as are the older style models such as the Rohmann and the MC5000.

Really, that is interesting to know.
I had one dealer who said its not a good match, they carry everthing but SME and the other said, its ok, thanks for the observation. I will definately look into it. I am using the 2M Black and its ok, I know I need a better cartridge since this was just a temporary setup, I do like the Koestu Urushi very much with the SME arm since I have used the Koesto with my SME4 arm before with stunning results and even some of the Grado under $1k did well. I have to look at the more costly Ortofon to see how they work with the SME
