One more question, if you know – if I enable it in both “Headphone EQ,” and load it and enable it in “Parametric EQ,” will that result in a doubling of the effect? EDIT: From listening I can tell the answer is yes. Very neat tools. Thanks again! ---

This is the first time I’m seeing this. Not to cast doubts on your experiences here as to what’s better, but I actually expect this to be more down to a difference in units the EQ was devised on (or revisions… who knows really) than anything else. I want to state loudly and emphatically that **you should not expect to get the perfect result from using ANY EQ profile, period.** There are many reasons for this, which we’ve gone into at length in various videos, but the point here is that an EQ profile shouldn’t be the end of the process. And more importantly, the more fine-grained the profile is, the more likely you’ll run into error - error in terms of things like unit variation, error in terms of in-situ response variation, error in terms of revisions… it’s an absolute minefield. And speaking anecdotally… I’ve been digging into some of these Roon EQ profiles and found them to be extremely hit and miss, even the ones done by Oratory. Like the one for the FT1 sounds absolutely atrocious to me. This doesn’t mean his profile is ‘bad’, it just means the in-situ response for the unit I have here isn’t a good fit with the response the profile was devised for. And once again, it is a better headphone where the EQ you have to do is minimal, and only requires wideband adjustments, because those are far more reliable and likely to be more predictive. ---

Yes the less fiddling the better I have found!! 😊 To be honest I was fine with the Edition XS before any EQ’s arrived and when I use the WiiM directly to switch them in and out as opposed to Roon there is no gap, no pause… and I have to listen really hard, to pop music mostly, to hear a difference. As I listen to classical exclusively on headphones then it’s much harder to hear a change. ---

Almost 4 months after the launch of Dan Clark Noire X I still can’t find it here: > **[OPRA/database/vendors/dan\_clark\_audio/products at main · opra-project/OPRA](https://github.com/opra-project/OPRA/tree/main/database/vendors/dan_clark_audio/products)** > > OPRA is an open, community-maintained directory of product information and EQ compensation curves that optimize a wide range of headphone models. - opra-project/OPRA Or do I need new glasses 🙂 Torben ---

I don’t think it’s there. (Search result below.) The good news is that the Noire X doesn’t need EQ. 🙂 ![image](https://us1.discourse-cdn.com/flex016/uploads/headphones/original/3X/a/b/aba9d687407a33ad0dc93861e6506a4f53f382b8.png) ---

@Spearthrower_Owl - Thanks, but I don’t think it is Noire X Torben ---

I don’t use any EQ with my Aeon2 Noire, prefer them without. Do use the OPRA for my MPS 145 IEMs used with ARC [Previous page](https://forum.headphones.com/t/roon-opra-eq-tool-and-data-repository/24606.md?page=1)
