Interesting! So they're not even toroidal. But similar to Hammond 229 series. I always liked the sound of 229. Hmmm...
Hello,
I think split bobbin will create a kind of filter to prevent all kind of noise from the primary side going into the dac. It appears some dacs also produce noises that will pollute your mains going through the transformer.
Toriods are usually used because they are cheap. Most companies are in the business for money so they want their parts to be cheap.
Of course outside should be bling bling to impress your relatives.
Greetings, Edward

Hammond 228 is the one I like; but only 48va. max. No small toroidal come close to 228; R core, and split bobin .
Rude arrogance? You and many other believe you hear a difference even when there is none. I'll start believing what others hear when I start believing in God, when there's proof. Double blind test or call it an opinion. And what's the old saying, "opinions are like ********...."
Let's stay away from religion and keep things polite, OK?
Even though the above was probably tongue in cheek, it pretty much sums the situation.
Were transformers as easy for the general audiophile public to replace as a power cord, their inherent sonic character would have been much better understood.
And yes, if are blessed not to hear differences between power cords, there would be little point auditioning transformers.
Transformers are far more audible than cable, simply because there are a lot of possible problems in transformers construction, implementation and Physics.
So your saying the "sonic character" of power cords is well understood? What would they be and what exactly in the power cord makes the difference. If you can't answer these simple questions I can't believe you. I call bs. And the post you refer to didn't say he believes in these differences he is saying if people believe rocks on your speakers, green felt pen on the edge of your cd and many other nonsense audio fool tweeks (like $1000power cords) then they will believe anything, including power transformers have "sonic signatures".
Power cords I suggest
- no lace,
- no big diameters (as thin as possible - less *noise* and less *distortions* result in cleaner *sonic*),
- no unnecessary connections (no extra fine and expensive plugs or devices with extra, with fine expensive silvered, coppered jacks - result in less scratchiness and rumbling - except you listen per multiwayspeakers,-)
Trafos too.-)
DAC - resolder, new-solder the device, except the analog sections, and listen,-)
Much much work, much much to try, to proof...

Random resoldering is an excellent way to stop electronics from working.
My own power transformer comparisons
i have a subwoofer crossover where I experimented with different transformers
Stan warren of ps audio fame once tricked Paul McGowan with his new mod
Jaw dropping
What was it?
Bigger transformer In Same circuit
In the legendary pooge audio amateur articles miller showed that the signal international dual primary and dual secondary transformers split bobbin transformers passed the least power line noise
I tried a 175 va triad equivalent with only 45 pico capacitance
Much improvement over the torroid that came with the crossover
Then I moved up to a 200 va r core from China with a shield and grounded the shield
It has a softer more delicate sound
Recently I had another round of comparisons
This time a huge 20 amp dual primary dual secondary Hammond split bobbin
And the new triad medical torroid step down with shield at 250 va
I have a laboratory grade dedicated ground for the shield
The triad toroidal had the most finely delineated sound and hugest sound stage and the most drive
But it added an edge to vocals and sounded less acoustic
The split bobbin triad had 45 of
The Hammond 250 pf
And the new torroid with shield almost 480 pf
I talked to ken Stevens of cat fame
He says there is a trade off between capacitance and magnetic coupling
I ultimately went with the 266 series Hammond even though 250pf capacitance is high for a split bobbin
It made the entire system sound bigger and more forceful and more emotionally involving
I'm happy to get away from the r core sound
We all want to be scientific
And I'm all for it
But ultimately it comes down to listening which is very subjective
Everything has a sound
You just have to decide how fanatical you are willing to be
And whether it matters to you
But you will never achieve greatness unless you listen to every part and wire

Did you measure any parameters use a scope or anything or is this just on sighted listening...
If something changes then there has to be a reason, doing measurement's and proper testing (DBT) will show this, anecdotes and hearsay just make it more of a joke......
