I think that calling SR a scam and a con tells more about the writer of the OP than is does about SR. madavid0 may not have heard a difference but does that mean his opinion is automatically upgraded to universal truth that will apply to the listening experience of everyone? But considering the switching shenanigans he reported on, these may be valid observations.
Synergestic Research: SCAM
Well, I just sat down to a demo of several Synergistic Research products including the Black Box room bass resonators, their new line conditioner, their active Tranquility Base, little treble resonators and the Atmosphere room acoustics tuner.
Total scam. Never once did they just play a track while moving things around. It was always a few seconds of a track followed by a 30 seconds of so of moving stuff, etc, then another maybe 30 seconds of sound. They'd start a track and then stop it right as some instruments came in, do the change, and then continue playing where it left off. The guy doing the demo was asked twice if he could do a live a/b and he'd give an excuse about how it takes a little time for system to charge or some bs like that and the transition process would mask the differences. Absolute con BS they are DEAD to me.
Also? I could hear JACK SQUAT changes in the demo. A few people around me would comment on the changes but I could hear nothing -- at least as best I could manage with the small clips and pauses in between changes. I really tried, but I could hear nothing.
Here, I took a video of a part of the demo. I'll post it when I have a chance.
