Neumann MT 48

and using the optical output with cheap DAC or ADAT to S/PDIF converter to digital speakers like Neumann KH120ii's - all controlled by the volume control.

I forgot about these extra 2channels via optical out + another DAC. Can use a good cheap Topping/SMSL DAC which has balanced output and excellent jitter with TOSLink input

Like Topping D30III

If you cross-check, this formula is wrong.

I compared PEQ for my Hifiman Sundara using Amir's measurement and EQ here and the shape of the curves didn't look like what shows in REQ (same as Amir's curves).

I tried to tell them it is wrong. Seems nobody there checked.

Well, that's frustrating.

I'll reply to the service email and suggest that they double check the formula.
We'll see if/how they respond.

EDIT: I have sent a reply to Customer Support (including pictorial evidence) demonstrating the discrepancy in the formula provided.
I'll report back if/when they reply

Did you verify yourself? Do you agree with me?

I do need someone else to check, in case i made an error

Music 1969,

Yes, I verified (using an Oratoy 1990 graph and comparing it to a graph created using the conversion formula provided by Neumann customer support)
This test did indicate significant discrepancies between resultant graphs.

As indicated above, I sent my results to the customer service agent, asking for an engineer to review the formula.
We'll see if/how they respond.

Again, I apologize if I have inadvertently spread incorrect information.

No problem, thanks for checking. It seems Neumann is spreading incorrection information also

Also worrying they haven't even checked

After a follow up inquiry, I did receive an update from Neumann's customer service.
However, it was simply a vague promise that the ability to import REW data is "on their roadmap," and they requested more information about my specific use case scenarios.

I pointed them to Oratory1990's database, as well as providing them with my own room-correction REW data.

So, while it was disappointing that they were unable to provide a more correct conversion formula, or immediately address the issue, I am cautiously optimistic that they will continue to look into this issue.

Perhaps, if more people would request this feature (the ability to import REW eq exports) or even a corrected EQ conversion formula, that may bump this issue up on their priority list

However, since it has already been mentioned in this thread that others have tried reaching out to Neumann about this issue, and didn’t receive a reply, I am a bit skeptical we will have a solution anytime soon, and that is frustrating

I will, however, continue to follow up with my email exchanges with customer service and post any relevant progress to the thread
