I’m sure there are hundreds, if not thousands of roon users who use both headphones and speakers. Many of us likely have a totally different listening rigs and endpoints that are exclusively used for each. For instance I have an endpoint on my nightstand used for HP listening. I also have a ‘sub-rig’ in my main listening room where I use a separate DAC, and HP amp for listening.
I was thinking, it sure would be nice to have a simple switch on the ‘Now Playing’ screen that would toggle the HP EQ on and off. Perhaps right down on the lower right by the little speaker icon. I know it’s only one-level down in the menu, but I’m always forgetting to turn it off when I’m listening from a speaker-located endpoint - and wonder why my music sounds so different.
Another user even suggested another option that would be even better. Tie the HP EQ switch to a specific end-point. The user could assign the HP EQ switch and a default HP/filter at the endpoint level. Perfect solution.
OPRA headphone EQ is a MUSE DSP function just like all of the other DSP functions and, as a consequence, it is configured on and endpoint by endpoint basis. For endpoints that don’t require headphone EQ, simply remove the filter (as I will now have to do after temporarily adding it to my headphone endpoint setup):
Note: Whilst I looked very briefly at OPRA when it was introduced, I did not end up using it for my headphones because I was already using a convolution filter based EQ correction obtained for my headphones from one of the headphone measureing sites that are now employed by Roon as the source for their OPRA corrections.
OPRA, whilst it would have provided an ease of use advantage on first setup compared to the convolution filter solution, did not offer any other advantage and so I did not change over. Howevr, if/when I get a new pair of headphones, then OPRA will likely be my first stop for an EQ solution - it’s just so much easier.
What he said. The only issue is if you have a speaker driving endpoint that also has a headphone output, in which case you do need to select/deselect DSP as required or have two endpoint DACs in that room. A RasPi can drive a DAC via a HAT and a USB DAC separately so this is easily achieved with no switching necessary.
