Jason as "cool" as this sounds, I'd like to consider myself and many other Bose owners as somewhat of an audiophile. That being said "we" would be more interested in our systems supporting better audio formats, IE True Dolby HD, Dolby Atmos, and the higher end DTS formats. I recently bought a ST 520, a Samsung UHD and the Samsung UBD-KM85, and while I fully understand that a true Atmos system requires in ceiling speakers or other additional hardware. That being said the 321 GS Series III that my 520 is replacing does support Atmos and it's only a 3 spearker system, and yes there is an incredible increase in the sound processing quality when an Atmos Blu Ray is played on that (321) system. I currently own two soundlink III's, a Bose bluetooth series II (the deleted one for cellphones) a 321, a Bose Solo (unimpressed and giving it away) and a Companion 5 (very impressive for what it is. My point is this, as Bose systems have evolved there is ZERO scalability or connectivity between the systems. I see the advantages to soundtouch to help with this but going forward I can no longer afford to buy the latest system and have to figure out what to do with the one it is replacing. Bluetooth should be bulit in, not an add on. The systems need to be more compatible with other formats and hardware. ok, im done for now, please address all of my talking points, not just the ones that are "easy" thank you for what you do, and your time.....
