Thanks for the review @edwardsean and thanks for the feedback @musicreo.
Yes, I agree that the levels are low. I used to have them set higher, but beta testers reported getting clipping during loud passages and especially during loud action movies, so I lowered the levels. I will have to do some more experimentation to find how high I can adjust the levels and still avoid clipping.
I suppose, if people are getting clipping, they can lower the levels in the Out Of Your Head control panel, but I didn't want people to hear clipping "right out of the box" so I lowered the levels to be safe.
Just to make sure though, there are many places in Windows to adjust the levels. However, it's pretty easy to check to see if it's just Out Of Your Head that is low. If you quit Out Of Your Head and you get good levels, then you're various Windows and media player levels are probably fine. Then once you run Out Of Your Head, yes, the levels will drop, but they shouldn't drop as far as 9dB. I find that for sensitive IEM's on my HRT MicroStreamer, I have to keep the Windows playback level to about 25% for normal listening levels even WITH Out Of Your Head running. However, with my HD800's on the microStreamer, then I have to crank up the levels. Of course if you are using a headphone amp with an actual volume control, then you should have plenty of level on the amp. But for small USB DACs that are using Windows for volume and USB power, then I can see that you might have to have the levels set to max.
As far as equalizing the levels between presets, I do need to go through them and adjust them, but due to the nature of how the preset levels are set, I can't do it in real-time. I have to set a level. Run a batch script to create the preset file. And then load it and listen. If I need to adjust again, I have to repeat the whole process. It's not impossible, just tricky to do.
Alternately, you can also adjust the levels down in the Out Of Your Head control panel and those levels are saved. So everytime you go to that preset, the levels you had set will stay persistent. This is a good way to fine-tune the level matching for your ears and amp between presets.
When i used the egyptian theater setting the output for LS/LB seem to be much to quiet compared to the RS/RB speakers.
Sometimes the channel imbalances can be due to the shape of your ears compared to the shape of the ears of the person's ears that were used to make the measurements. Unfortunately, without doing a custom measurement with your own ears, some people will experience differences like channel levels, speaker positioning, frequency response, etc. I knew this going in to this project that some presets will not be perfect. But, I continue to add to my library of measurements and not just with my ears but with other people's ears. As the library of presets expands, hopefully people will be able to find presets that work better for their ears.
On some rooms, like the Acoustic Zen room, I have measurements done there with about 5 or 6 different people. I plan to create separate presets for the same room but with different people's ears. This way you can try each one and hopefully one will work well for you.
For the most discriminating users, I would invite them to come to Southern California and have a measurement done with their ears. I know this can be an expensive route to go or impossible for most people, but it still can be a lot cheaper than buying a Realiser. People fly to meets, shows, etc. just to hear gear, so maybe it's not out of the question for the "summit-fi" people.
But for channel levels, you can experiment with adjusting the levels of each of the channels in Out Of Your Head to suit your ears.
