I don't know if you have available ear drops with Ofloxacin plus dexametasone, they could help to speed up the inflammation control, hence the pain. Ear pain is really bad. Drug yourself
Pull the pinna back and upwards, not the lobe. That's what will align the canal with the timpanic membrane
10 drops? That's way too much, just 3-4 drops is enough. Before applying make sure the liquid is at body temperature. The tinnitus should improve once the inflammation (being in the external or middle ear) is gone. How about your hearing?
I guess that the other advantage of getting the signal balanced from the mic is having twice the voltage, once you sum the legs. Considering they're tiny signals...
I'm using the plus. I tried it, compared it to Decibel, Amarra and a couple more, then decided it has a decent price-performance ratio and paid for it. I don't use iTunes--just to feed the iPod--, and have a good lot of DSD, 24/88-96 and FLAC files, so it filled well quite some needs.
I could live with that hadn't other amps, but some of my friends who listened to the combo (who by the way love the O2) found the HD800-B22 pairing unlistenable. To each one his own, I guess.
