I'll echo Thomas's comments elsewhere about Amir going to all this effort to document what was at the show - it's time consuming, fiddly, and probably was thoroughly irksome by the end of it; I appreciate the energy and thought that went into it, thanks Amir.
Just to add to a previous post where I mentioned a YouTube channel with decent quality sound bites of some of the gear,
https://www.youtube.com/channel/UCpZH8wRfvZq4x9hTP2exH-g: this has been done in about an unprofessional manner as possible, terrible camera technique, no titling or comments - but, 192Kbps audio quality, and it's easy to hear the benefit; contrast this to Peter Breuniger's
https://www.youtube.com/user/AVshowreports where the apparent contrast couldn't be greater - but, Peter has still trapped himself into 126Kbps sound, and his first system clip from there, just posted, does no favours to the rig, as a result.
