For what it's worth, my last pair of digital aids were purchased circa 2011 as well, and the pair I recently (last few months) got aren't just better, they're astonishingly better. I ended up going with Phonak Audeo M's over the Starkey Livio AI's but it was a close decision. My two cents is that if you've got the inclination/resources, it might be worthwhile to pay a visit to an audiologist you trust to see what the state of the art is like.
I recently made a similar upgrade (old ones from 2010-ish) and I was also impressed by how much better the new ones were. The old pair's performance may have degraded over time, but the way the new ones blew them out of the water I doubt it was just that.
The Audeo M's (are? were?) the only ones with native, in-device/streamer-less bluetooth. They work just like bluetooth headphones/mic (used so far with: osx, android, linux desktop) and the sound quality is outstanding. The only minor irritant I've found so far is that you have to effectively power cycle them to re-pair to another device (eg phone to work laptop).
