RME ADI-2 Pro AD-DA Converter and HiFiMan HE400i Headphone - Close to perfection

Are you going to use the Analogue output from the RME dac and feed it to the D1 I/V stage? Is there some benefit in doing this?

Is the Carbon Amp the one from Cavalli?
Not Cavalli, it's a Soren Brix build.

My limited understanding is that the analogue output would be replaced by D1 I/V, not fed to it, but I may have just written something that makes no sense.

Regarding the benefit, I don't know, there might be no benefit at all--that's why I'm online reading about the topic.
 
If you or your friend can design an I/V that's more linear than what RME has, a Nobel is waiting for you.

Well dang it. I'd like to respond that my friend is convinced the RME I/V can be improved, and that this friend has friends who agree, but I'd only be parroting them.
Does this qualify? 🙂
For a Nobel?? Geez, I don't have enough expertise in this area either.
 
A good check would be to ask him for a schematic of the RME I/V and if he can point out what is the problem 😎
Opinions are a dime a dozen.

Thank you for being blunt, it's appreciated.

Full disclosure, he already gave a detailed explanation...several times and with patience...that I didn't understand. I took a bunch of notes that turned into several hours of googling.

Should I take it that you don't agree with a benefit from an "improved" power supply for the RME as well?
 
I don't know the RME power supply. But these things are complex systems.
You can't just replace one part in the hope that the system gets better.
Years and years of engineering-design hours goes in such products.
The idea that you can change a regulator or an I/V and all of a sudden you have a better product is, frankly, ridiculous.
It's like changing a bearing in a car for a more expensive one and expect a better car.
More likely there are consequences you're not aware of (and you cannot be aware of) and you break something.
The RME is a ($ 1600 ?) exquisite piece of engineering. Don't violate it.
