I haven't seen any company producing highend digital equipment using R-core transformer though.
Really?
What kind of 'digital' equipment? Dacs?
What would you suppose the benefits or drawbacks would be to using R-Cores in digital equipment?
Follow Ups:
Cary makes some high-end CDPs with R-Core power transformer. I've owned a few Cary players over the years. I'm sure there are others using R-Core. E-Stat already mentioned some.

: CD Transport and DAC yeah.

: Benefits of R-core in digital equipment? Maybe you can build smaller size DAC with higher VA. I think toroidal transformer is more suitable for digital equipment with lower noise.

Interesting.My Dac's have R-Core.
Is it your opinion that Toroidal is better than C-Core too?
It was my understanding that low level source components benefit from R-Core.

I'm talking from my observations with highend CD transport and DAC I know in market. What is your DAC by the way?
What about Phono Stages would they benefit more from Toroidal too?
Wonder why Audio Research put a R-Core in their $7,000 phono stage?
Is that digital equipment?
Maybe in all the excitement you missed my question.
"What about Phono Stages would they benefit more from Toroidal too?"
It depends on design. Some works better with toroidal and some on R-core. As I told you, toroidal is good with lower noise and R-core can provide more power efficiently.
My $2k phono uses EI transformers and I have nothing against that. I never say which one is superior. It's just all highend digital sources I found either use switching or toroidal transformer.
Would you consider Audio Research Hi-End?
Audio Research builds famous highend preamps. But I haven't seen anyone using digital sources from Audio Research. Well, if they did make products at scale like dCS Vivaldi or Esoteric Grandioso, I'd love it hear them too.
Audio Research makes the full range of audio gear from Dac to CDP to Phono stage, Preamp, Amps etc.
Even some of their preamps use R-Core like this SP20
I use $20k SACD transport + DAC from company being famous on digital audio. If you understand what I mean...

Oh ok, Hi-End = $20k+
Got it, thanks...!
Given the laws of diminishing returns, that extra $19k gives you about a 1% improvement in sound...if that.
I bet it looks good though and makes for a great conversation piece..:-)
If $1k can sound good like 99% of $20k, I wouldn't have bought $20k equipment.
Anyway, Audio Research is company specializing in analog products. They may have their reason from analog perspectives. Now I know there's Audio Research using R-core on some of their digital equipment too. Thanks.
If $1k can sound good like 99% of $20k, I wouldn't have bought $20k equipment.
LOL!!!!
You'd be surprised.
Winner take all bet....hypothetical of course.
Connect a $1k product [digital front end] to your system along side your $20k [digital front end]. Let 10 people do a DBT, if 6 or more pick the $1k product you loose your $20k product.
You willing?
Since this isn't in my field to talk about, I'll end our discussion here.

.
It's "Confident".
LOL....
I got too excited...
The prospect of winning a $20k digital front end and all....
:-)
I totally get that. I used to get too excited thinking my modded $1k DAC can sound as good as those highend CD players. :D
Have a great Friday and a wonderful weekend.
Let me go try to calm down.
You should try modding your $20k gear.I'm sure you can find something that could be improved.
I bet I could...first thing I'd do is change those transformers to R-Core.
Edits: 03/17/17
I did. But I changed from switching power supply to linear power supply using ultra low-noise toroidal transformer though. ;)
Edits: 03/17/17 03/17/17 03/17/17
And that made it sound better?
Do you also put ketchup on Kobe beef?
I've never heard a Toroidal that wouldn't make a good door stop. Who makes them?
It sounds better of course.I didn't put ketchup on Kobe beef.
I don't know.
Edits: 03/17/17
You modded something with Toroidals and you don't know who made them? Did you buy them off of Ebay or something?
Impossible....share the secret, I might want to try one...that is if I can afford it.
I don't know Toroidal that wouldn't make a good door stop. For my transport and DAC, my technician friend used toroidal transformer from Talema at that time.

Maybe my Dac is not considered Hi-End...:-(
