Confusion about ZMC and SUTs
02/09/20 at 02:14:26
 
Iím new to SUTs. Iím still undecided on what cartridge I want to end up using. (Cart specs at bottom) issue is they are a little different in the resistance specs.

The ZMC sales page lists 3 different versions. For the Soundsmith the ZMC1 looks like the ticket. The Benz is 38 ohm DCR. This is higher than the recommended cartridge ohms. Would the ZMC1 work well for both cartridges?

Iím guessing the 20:1 ratio would be the one I would want?

What would the loading range be for the 2 cartridges be?

Will the ZMC1 work well with both?

My understanding is that the cartridge DCR is part of the loading equation when using SUTs.

Benz Ruby 3
.34mv output
38 Ohm
recommended loading 500-47k ohm

SoundSmith Zephyr MIMC (Star)
.4mv output
10 Ohm
recommended loading 470+ ohm

I didnít find a manual for the ZMCs

Thank you much!

Extra info that isnít directly related to the question.

Iíve owned the Benz Ruby 3 for many years and am happy with it. Iím guessing itís time for a retip / rebuild. Issue is itís in storage in Denver CO. Iím currently in the Philippines. When I do go back to visit the USA I will be in the Philly area. So between the travel cost and the cost to retip I might be better off getting a new cartridge. Thatís not even taking into account the time cost.

Iíve heard good things about the Zephyr. It seems like it would be a good cart to hold onto. I also like the SoundSmith rebuild price.

Any reason why you arenít considering high output cartridges (2.1mV)?  I have the SoundSmith Voice and I go directly from my turntable to my ZP3. I wanted to avoid a phono pre-amp and another set of cables and connections. I am delighted.

Steve recommends 4mv+ into the ZP3.

With the ZTPRE Iím guessing you have so much gain the below 4mv input isnt an issue
Do you ever run out of volume with 2.1mv?

I agree it would be nice having less cables and boxes.  0.4mv with ZMC1 would be 8.0mv into the ZP3. That sounds like it would make everything happy.

Iím going to be running ZP3 -> ZRock2 -> Toriimkiv. So I wonít have as much gain as you.

I had a ZSTAGE in the mix for a while but found I did not need it. I have plenty of volume and headroom.

I've been going back and forth if I should go the low output or high output MI from SoundSmith. When I get back to the states in March, I'll give Steve a call and report back about his recommendations.
