Jon, I am so sorry to hear about this. I have just extended the lease on my 2013 Acura ZDX for another year, just so I can hang on to the DVD-A capability. It's my third Acura with ELS (had two TL's before this), and it will be a huge loss when it's finally time to say goodbye.
Out of curiosity, how is the stereo sound on your new system? I am considering a 2017 MDX, but also thinking about a Lexus RX with the Mark Levinson system, if I have to be stuck with stereo listening (I stream all of my music from my home server to my iPhone at full lossless quality).
Well, IMHO, the AM/FM and iPod playback (in stereo of course) is nowhere near as good as my old car. Frankly, it sounds cheap. However, by futzing with the EQ controls which goes where years of training have taught me not to go, I have the DTS CD playback to the point where I think it sounds pretty good, at least with the few discs I've made so far - Fagen, Steely Dan, Assorted tracks, etc. Turning the ANC system off helps a bit but is a pain and until I can disassemble the dashboard and rip that unit out I am going to have to live with that most of the time.
For anyone who was choosing Acura's solely on the basis of the ELS surround audio system checking out other cars in that price range (Audi, Lexus, infinity, etc) would probably be a good idea. If I still have a job in 3 years (and am still around) I will surely check out everything as my allegiance to Acura is about done at this point. Of course by then a disc player in the car will be a relic.
