Which SUT? .... for .3mv/10 ohms MC cartridge into 3mv MM input sensitivity


Please help me choose a SUT for my 1st MC cartridge.

Now I have more than enough volume using my existing MM cartridges thru my mx110z MM Phono input which says sensitivity 3mv/47k ohms impedance.

AT440ml is 3mv.
Shure 97xe is 4mv
Shure V15VxMR is 5mv
Grado ME+ Mono is 5mv.

coming tomorrow: AT33PTG/2 MC .3mv/10 ohm coil impedance/dc resistance

..................

signal boost, am I getting it right?

1. Is 3mv a MINIMUM strength for the mx110z input?

2. .3mv x 10 = 3mv (+20db correct?) (minimum boost therefore x10/+20db)?

3, if correct, is .3 x 20 = 6mv equiv to +40db?

4. if so, a SUT providing +40db is more than enough for the .3mv and any likely future MC?
.........................

impedance/loading: I am not getting it.

I read about a general rule: coil impedance x 10 for ____?
A33PTG/2: 10 ohm coil x 10 = 100 ohm

too high impedance sounds thin? bright?
too low impedance sounds dull?

(how?) (minimum?) (where?)
......................................................

Thanks as always, and this time I will definitely wait for advice before getting anything. I am not in a hurry for this, Bill will loan me one of his SUT’s until I get my own.

thanks, I'll check it out. I get the earball thing, now that I realize what it's all about.

I've resisted even mouthing the words Moving Coil since they needed humming boosters when I was young, it is all new to me. I enjoy learning, and sharing my finds with 'imagined' others.

I'm a retired Interior Designer, specialized in Corporate Headquarters: New, Relocations, Renovations. Interior Architect  actually, as practiced in NYC, PA, Wash DC, traveled hither and thither. I became more informed bit by bit progressively for 50  years. I researched everything, designed much custom work, selecting, presenting options to my clients, ordering a gazillion things. Select and present a full line of chairs, mail room to President's office, for a new 250,000 sq ft headquarters project, it's exhausting. I was not going to tell a client 'this is the best choice', and find something 'better' that I didn't know about a week later.

Now, for myself, i.e. that Fidelity Research FR-4. It truly appeals to me, and it did not pop up in my search until after a lot of searching. No one mentioned it. New, it's features and quality, would cost ___? It's hard for me not to 'add to cart' and put this search to bed.
Demagnetizer, who loses sleep over this?

Miyajima Labs sometimes include demagnitizing built in

"When several months pass, a stepup transformer and the cartridge are magnetized.
The demagnetizer short-circuits ... "

If true, couldn’t I use my demagnetizing wand for my reel to reel decks for this?
You may want to do some reading here. I think it will help answer many of your questions, and answers to your questions, about cartridges and SUT. Lots of great info on all things hi fi.
