Gain setting on Rega Aura with Apheta 3
Gain 1 is 69.5 dB,  Gain 2 is 63.5 dB.  The Apheta 3 has an output of .35mV.   The best choice would be Gain 2.  You should set the impedance load to 100.  
Need a sut for Hana ml
Granted, there are some MM phono stages that are not the standard of approx 40 db and approximately 47k ohms.  If it is not a standard MM input, then I stand corrected.  However, my statement stands.  The ML at 1:20 into a standard MM phono stage ... 
Hana Cartridge for MMF-7 ?
Get the Hana SL and use the 1:10 SUT 
Need a sut for Hana ml
I have used both the Hana SL and Hana ML as demo cartridges at audio shows, and have experimented with many different step up ratios.  The Hana SL is perfect at 1:10.  The Hana ML is perfect at 1:20.  I highly recommend 1:20 with the ML into MM in... 
Anyone heard the Don Sachs Custom Tube Phono Stage?
I use Chinese tubes and a GE tube on the line stage. On both the Don Sachs phono stage and the Hagerman trumpet MM phono stage, I am using amperex bugle boy tubes.   Upon close listening, I slightly prefer the Haggerman over the D Sachs phono.  I ...

8 track tape vs 1st press vinyl
The best copy of let it bleed that I remember hearing was on an 8 track In a VW beetle.   It might’ve been because of a chemically altered state of mind.     
Looking for phono preamp suggestions
Don Sachs makes and excellent phono stage.  He builds them one at a time.  He is known for repairing vintage tube gear.  I would be willing to bet he would build you a Balanced phono stage. 
SUT vs. Phono preamp
With a Moving Coil Phono cartridge, you should use an external Moving Coil (MC) step-up transformer into a Moving Magnet (MM) phono preamp or MM inputs, versus using a self-contained phono preamp that has both MM and MC inputs. Background: Match...

I use a 1:20 step up with my Koetsu RSP and it is a perfect match.   
Anyone heard the Don Sachs Custom Tube Phono Stage?
I have 2 of them.  One I use at home with the Don Sachs line stage.  The other I use at audio shows to demo the Bob's Devices Step up transformers.  I have used many phono stages in the past and like this one a lot.  I also currently have a Hagerm... 
Do any of your Rolling Stones recordings bring "Satisfaction"?
The best it ever sounded to me was in a VW beetle around 1970 when played on an 8 track, while everyone in the car was stoned.  Since then, I my favorite recordings are from a German Decca box set entitled: "the rolling stones story." 
What MC cart would you use with this setup?
since you like the 2m Bronze, why not go for the Cadenza bronze?   Another alternative is to send your 103R to Soundsmith for a ruby cantilever / line contact stylus refit.  I have personally tried both of these.
