I actually think itās a pretty nice feature and it works nicely over here!
Just one question: Trying out some of the EQs, Iām noticing a volume difference, so it seems that headroom is already built in and does not have to be set additionally. Can someone confirm?

For my purposes (a number of headphones that stay connected to specific endpoints for long periods of time, but which do rotate 1-2 times per year), this is great. Thanks for doing.
I agree itād be nice if there were a suboptimal but possible way to interact with a feature this simple (just pick manufacturer / model, not define your own EQ settings) from the phone app, but for my purposes itās not a killer. Clearly for some folks this is important. I am in the camp that would like to be able to do more things rather than less from my iPhone (ie, smart playlists, simple track editing / identification) but I respect the choices that are made. I do think that there is a measurable segment of users who are ~99% phone as remote, and for them these phone limitations must be a real pain.

ARC seems good to me with OPRA.
Although my first use with standard Roon for Ferrum WANDLA and HD800S results in OPRA reducing volume considerably.
At first I thought it was really muffled, but turning volume back up I think itās back where it was.
It felt the equivalent of a -12dB headroom adjustment and so contrasting with the no OPRA option that itās really hard to A/B test.
Could be great for ARC, but without a decent way to test Iām not sure I want to just try it.
Will try MojoPoly later.
Maybe speak for yourself, there are many users here who are 100% headphones. I have been for at least the last 12 years since I retired.
There are many advantages to using headphones , if you have restricted yourself to Cell Phone & Ear Buds you have been serioulsy missing out

Hi, This is sound very good. I did try to found OPRA in Muse without success. There is only AUDEEZE option that I can see. Can someone provide some guidelines? Best.
I know many people that have more invested in over-ear headphones than most do in stereo gear. This is a huge win for Roon.

Well, are you using Early Access updates for testing?
Thank you for the information. In fact, Early Access Program is new for me. I got the information on the way to install the Apple app to get access to Early Access Program. I will install it and I will provide feed back. I did set the Headroom for my Audeez LCD X and I can hear the improvement. Thank you.
Remember that you have to update server and control apps (on PC and mobile) to Early Access. If you donāt intend to keep testing Early Access (and deal with the occasional issue), itās probably better to wait a few more days until itās released regularly anyway. Itās usually only 2 weeks or so until Early Access updates get moved to Production. (Depending on how many bugs are found and how the feedback is in EA).

Thank you for the tips. I will wait in order to avoid local network issues. Since it is working with my AUDEEZE LCD X I can expect to get interesting results with my other headphones. 
You can already add PEQ manually, OPRA offers a degree of convenience and simplicity.
I personally prefer the Oratory1990 presets which you can get here;
There are other sources of PEQ settings, should you feel your headphones need them, not all do IMO and some actually make headphones sound worse, again IMO.

Like British rhyming slang, you need to be aware to get it.

Think on the following, @mike.
When an EQ preset has been chosen, the signal path display should be enhanced to display the name of the preset, possibly as a widget that collapses the individual filters in the pipeline. I suggested this many years ago as thereās not enough information in the signal path display to distinguish between presets that have the same filters but different parameters. Displaying the preset name solves this.
This feature would be useful for OPRA users as a place to find the name of the OPRA profile thatās active in the signal path, and if expanded, which particular filters are in the pipeline too.
Thanks,
- Eric

OPRA certainly appears to be a great new Roon feature. Quite a bit easier to use than the convolution filter method. Now Iām just waiting for filters for the Drop+Grell OEA1 and the FiiO FT1 headphones to be added.
Bravo Team Roon!!!

Absolutely agree with this statement.
It has made it significantly easier to swap between headphones and also different filters for the same headphones when they have multiple options available

It is a very nice and helpful feature. Well done!

Mmh, I donāt see any advantage in using OPRA against the previous filters.
If you use a mobile as remote, youāve to save for each combination endpoint/headphone (Iāve a lot of them 
) this as preset and this work will be done (for me) only once, until a new headphone or endpoint comes upā¦
For endpoints, which are using HQPlayer I donāt use any DSP in Roon and so also not OPRA, but this is another pointā¦

The advantage is that itās made it easier to use headphone DSP for users who would have had no idea how to set it up previously by finding a third-party site for measurements, copying the EQ data, and entering them into MUSE.

I doubt Iāll use it, Iām not planning on buying new headphones and the 2 headphones that I feel need EQ have presets already added by me manually, but for anyone whoās not tried PEQ it is a quick and convenient way to try it
