Title: Step-Up Transformer with Hana & ZP3
Post by Buckaroo on 06/17/24 at 00:01:28

Long time user and lurker, first time posting. I am reaching out looking for advise from folks with similar experiences. I have recently purchased a Sota Cosmos with a Graham 2.2 arm and am having a Hana ml cartridge installed. This will be my first MC Cart. I went back and forth and decided to keep the ZP3 and add a SUT. The Sota folks have steered me toward Bobs Devices, who I spoke with. Seems like he has what will do the trick, but is it the best option for the Hana and the ZP3? Any advice is appreciated. Cheers

The best? Like a lot of stuff in audio you can spend an almost unlimited amount on step up transformers with increasingly exotic materials. But you could get a Decware MC1 for less $$$ than a Bob's Devices and I'm sure it will be fine. It may even be a little bit better because it has 6dB more gain than Bob's.

I personally have a Luxman SUT with my phono stage (similar to a ZP3) and it is super nice. Way nicer than any of several MC phono pres that I've had over the years.

I looked at Bob's SUTs when I grew tired of my Jolida JD9. Never read a bad review on Bob's SUT's. I ended up with a Ned Clayton cinemag 1254. I liked the idea of having multiple settings and this one has 1:10, 1:13, 1:20 and 1:40. Bob has some that switch, but the choices are limited. If you don't know the ratio you want, Ned's SUT is a good option. I'm using an AT OC9III cart which is similar in output to the Hana. I run mine at 1:10 which I never thought I'd use. The volume is slightly lower, but much more open and detailed. If you do know the ratio you want, then Bob is a good choice.

Ned sells through ebay and I don't see any current SUTs for sale. He sold one a few days ago, here's a link: https://www.ebay.com/itm/126527359374?itmmeta=01J0HTSXD76RKRP9P617RP535V&hash=item1d759e498e:g:xFkAAOSwAK9h1jtM

You can email him, he's responsive and helpful. ned.clayton at gmail.com which gets blurred out on ebay.

Well, that's part of my problem. I don't really know what ratio I need. Bob kind of brushed over that when I talked to him but pointed me to the devise that has a 1:10 and a 1:20. He said they would work with all the Hanas'. I have also looked at an Ortofon and a Hasimoto. Whenever I have talked to someone I get the 'this one will work, buy it', instead of explaining why. Im just trying to make sure that the SUT will work with the Hann and the ZP3. I guess finding one with multiple ratios may be the better approach. Thanks.

BIG fan of Dave Slagle at Intact Audio. He designs his SUT to be system specific and not a one be all answer. You don't have to do anything.
And of course his work is second to none.

Here's the math: A 10:1 SUT is 20 dB of gain, 20:1 is 26 dB. ZP3 is 42 dB and your cartridge output is 0.4 mV.

So with a 20:1 SUT you get 10^((26+42)/20) * 0.4 = 1 Volt output. A 10:1 will give you 0.5 Volt.

It looks like you are using a ZRock as a preamp, and I'm not sure how much gain you can get from it, but IMO you are better off with a 20:1 SUT regardless.

Ned Clayton is the way to go. Nice guy, excellent product, reasonable prices, more options if you make changes down the line. He's very responsive via email and will work with you to find any value you need.

Ned can get the same Cinemag transformers that Bob gets. I think Bob's prices are kind of insane.

I’m running the Hana ML, ZP3, and ZMC1 combo and it works well. I have not used any other SUT’s so nothing to compare to.

Thanks for all of the great info. I appreciate all the comments. I plan on reaching out to Mr. Clayton. Thanks again.
