Finally got around to experimenting with using the M11 as a very bulky and expensive bluetooth receiver....and it's pretty good at it! I'd say LDAC streaming from S10+ phone to M11 gives me about 90% sound quality while providing a small uptick in convenience. I'm using Campfire Atlas with the M11, and I perceive the bass to be somewhat less pronounced via LDAC, but it still sounds very good. On a separate note, I got the (faux?) leather case today from Penon Audio, and it is a nice upgrade over the clear case that ships with the M11. I came close to sending the M11 back to Amazon a few days ago in favor sticking with my LG V35, but decided to give it some more time. I'm glad I did, it's a nice device and worth the asking price.
