Miyajima Lab Zero Specs?

The coil impedance for the Miyajima Zero Mono is 6 ohms and the recommended loading is 200 to 300 ohms, I prefer mine at 300 ohms rather than 200 but your tastes may differ. The Zero can be a bear fro hum so make sure your system has either a mono switch (as the hum is usually thereby cancelled) or a ground lift option. I also got best results from a step up -- a MusicFirst Audio Classic V2 with 1:10 ratio and 80K to 10K parallel load options resulting in between 100-500 ohms seen by the cartridge. Load capacitance is generally not an issue for moving coils so I've never seen specs on this.

I agree about the need to tame the hum. I have been using a Benedict Hothead mm with Bobs Devices SUT and getting good results, but I have recently bought a Pass Labs XP25 and was wondering about the best settings for the Zero. I will also try the SUT with the XP25.

Ideally the Zero needs a step-up. If hum is an issue then a mono button (or a double-y connector) cures completely. Seems to be less of an issue where a step-up transformer is used.

I have three Miyajima monos - Zero 0.7, Premium 1.0, and Kotetu 78 3.0. They are all slightly different but work superbly on the 6 ohm setting of my EAR Yoshino 912 preamp which I think equates roughly to a 1:20 step-up. In my view they are better suited to a step-up transformer - certainly it sounded better in a previous setup through a Hashimoto HM7 SUT (at the lower 1:15 ratio rather than 1:30) into my Aurorasound Vida phono stage than direct into the MC input which from memory is about 500 ohm.

I had not heard about using a double Y. I'm going to try it. I take it that the double Y is between the SUT and the pre-amp?

... or is the double-y between the turntable phono cables and the SUT?

I would try both but suspect that between phono cables and SUT is the most appropriate place.

I realize that I am late to the party here but, for future reference I believe this needs to be addressed. 

Folkfreak1, I'm not quite sure where you get your loading numbers for the Zero, realizing that Miyajima, not at all unlike many other cartridge manufacturers does not make it easy and just thoughtfully list the loading for their products right on the website under specs but, from what I see with their many distributors about the planet, a loading of 100 Ω is actually what most all are presenting as recommended...
