What house curve you use, to apply to a flat calibrated/corrected sound, has naturally a big impact. I like a little extra warmth, which certainly influence my own house curve (which is applied on a flat room correction done in REW). It gives a sound similar to the new headphones I bough: B&W P7 Wireless, which I like a lot.
Here is my house curve for my active speakers, lets see yours
Thought I would go in a slightly different direction and share my current curve for my Elear HP setup (Schiit Jot, Schiit Saga, iFi micro, Roon upstream). The Elear’s are a great HP, but not out of the box as they positively require DSP for passable FR in my opinion.
The one you have there looks good, but I think its better to use it in REW and correct to it, and not use PEQ in Roon (the less DSP you have the better).
In REW you can use a textfile and select it from settings, this is the one I currently use which is a little “fun” and not strictly neutral (but feel free to experiment, house curve is very subjective):
Thx so much for sharing your house curve. I am Not able to share mine due to the fact that I have never used ones. However, I am happy to share those two posts, which discuss the opportunities to use them. I was really happy to get those informations. Although listening music for decades, I was not aware about those items. And I did not know that it can be modified by the roon application/filters.
For those that wonders why we need a house curve: its not just a listening preference, but physics/biology. Our ears hear low frequencies at a lower level than high frequencies which means we have to boost lower frequencies and lower higher frequencies in order to get a curve that to us sounds flat (but to a microphone has a tilt).
I seem to recall +5dB at 20Hz to -5dB at 20khz as a good neutral tilt, but then you can add your own flavor to that of course, like a little extra at 50-100Hz
You’d have to use Roon’s parametric eq filter in DSP and create the filter bands yourself but it’s pretty straightforward. I did this for my Meze Emyprean’s and it was a nice improvement. Of course the measurements taken from the headphones used to create the EQ might be slightly different from your own headphones …
For those more adventurous, you can buy one of these:
With this you can measure the response of your headphones exactly and use REW to create a matched EQ that you can also enter in Roon’s parametric EQ filter in DSP. I also did this and it was another solid step up in sound quality over the above…
