I wanted to bump this service as a few users on Devialetchat are reporting great results and may be useful for Roon users that want to try but don’t have the technical knowledge and/or desire/time to mess with filter creation.
Essentially you take measurements, and send them to Thierry, who is apparently highly knowledgeable in the field and creates filters for you using his allegedly proprietary software.
I have no affiliation, but it’s of particular interest to me as I was deliberating whether to buy Acourate to make better filters than my REW PEQ ones, or try and find such a service. I will almost certainly try a test with him as soon as I can make fresh measurements. It is a paid service just to be clear.
There’s a thread on Devialetchat where Thierry has also contributed, and some measurements (including with correction) have been posted:
