Can I ask how you got the update to work? I've tried to follow the directions (wish they'd get the ones in the package to match the ones on the website), and it throws errors about the file being a directory.Looking forward to v1.8.0 in iOS. the V1.4.1 firmware is working for me (16/44.1 in Windows 7). The iOS 1.7.5 app works ok with the new firmware, though the analog volume slider didn't initially match the actual level until I tweaked it. Some settings were reset (DCT off, oversampling off, buffer length = 0, EQ off). Perhaps 1.8.0 might have initialized differently, but it's not a big deal to me.
At some point, I'd like to see more than 4 custom EQ presets. I don't have any use for any of the pre-built ones (except FLAT), but I do have more than 4 headphones that I'd like to use with this device. Also, it would be nice if the Output Level Estimation could be linked to the active custom EQ setting (have impedance/sensitivity settings for each).
[edit] Another possibility: have an option to link a couple of the custom EQ presets to the bal/unbal configurations, respectively. I have two earphones that I currently am alternating here that are of those two persuasions.
I agree with most of SubMash's recommendations. #7 would be a great feature, if executed well - does the ES100 have sufficient hardware resource to add this?. There's a function like that in the 3rd-party Equalizer iOS app, and I used it there (before I got the ES100). It's helpful with mixed-album playlists, for sure. EQ preamp levels are quite disparate between my FiiO FH5 and Sennheiser HD 650, but I have a couple of tracks that cost me a few dB of the gain needed to volume-match the two.
EDIT: Nevermind. I moved the file out of the folder and lo and behold, it worked. Come on, Radsone — I shouldn't have to use the terminal to install a new firmware.
