To your taste, is the high frequency balance best with current DT-990 + current Voodoo sound, or would it benefit from a slight low pass filter to remove some brightness and air ?
I must admit that I can't really compare with the old situation as there was no way to drive the DT-990's at a reasonable volume on the SGS, therefore I never used it with them. With the Voodoo app set to just below full amp I don't even have to set volume to max in the MP3 app to achieve a good listening level (12-13 is enough).
I just did some side-by-side comparisons with the following tracks/albums:
Steely Dan: A decade of: Various tracks
American Beauty: OST: Dead already
Using as the reference hardware an iRiver H-120 with rockbox (firmware upgradable "open" hardware lasts soooo much longer, it should be made mandatory for manufacturers to allow/support 3rd party firmware). Although old, this is still one of the nicest bits of listening/recording hardware with SPDIF in and out!
Overall, the dynamic range on the SGS appears to be greater. The sound is also a bit brighter and with more detail. Having said that, the iRiver is a bit more relaxing to listen to which may be due to the smaller dynamic range and reduced brightness.
A caveat though; my DT-990s are more than 15 years old and my ears are pretty much ruined by listening to music too loud and too long.
My Shure EC2's sound a lot better with your patch too, much more precise (this I can compare with the old kernel).
Again, thanks so much for your great work!
* I never use an equaliser (unless I have to deal with really crappy headphones like the SGS original headset).
* Wow, I hadn't tested the radio, it sounds soooooo much better now.
