Soundsmith cartridges

What are the differences between the SoundSmith Hyperion MKII - MR (10k) vs the Hyperion MKII (8k)? From SoundSmiths website can't tell.


One wonders what the inductance of a low output MI might be, to render it useable with current driven phono stages. Very interesting.


I was wondering that also but I did not feel like bothering him asking for the specifics. He thinks the voltage mode works better so I went with that.

I’m thinking if you reduce the voltage output significantly, so that fewer turns of wire are needed to generate the lower signal voltage (and also resulting in a lower internal R and inductance), then it might be possible to mate the Hyperion to a current driven phono, but as you reduce voltage out, you need to hope for a greater loss of internal R and inductance, so as to get a net increase in current output at audio frequencies. You did the right thing; just use conventional voltage drive.

I was underwhelmed at first by the Sussurro MkII ES. I played with the loading and found it helped a bit, but it never really came alive until I used an SUT. At that point it became a very neutral but detailed cartridge, not quite as dynamic as a Decca, not as rich and warm as a Benz, but worth hanging onto for when one of my mainstays goes for a re-tip.

@dogberry, which SUT if you don’t mind my asking? I’m using the same cart while SS is looking at my Benz LP-S. I have it loaded at 825 Ohms with my XP-17 and I’m enjoying it very much.
