Apologies for resurrecting this somewhat controversial thread but I wanted to share my recent experience and get members' thoughts on it. I went to a recent demo hosted by Audio Group Denmark where a rep went through a range of their products. The system was a basic DAC-streamer-amp with floor standing speakers. It started by sounding quite poor and I was ready to walk. But, by seemingly adding various of their Anzus "noise reduction" products as listed in the posts above, I have to say the system started to sound pretty nice. Now, I like to think I can spot a "Barker" when I see one! And I fully appreciate that from an EE point of view their Anzus products suggest first rate snake oil. So by adding in these snake oil products, how are they able to improve the SQ of their basic system? I did hear an SQ improvement as did all nine of the other audience members in the demo and we were all pretty skeptical. So what's going on? Mass delusion or a conjuring trick? To be clear I am not advocating the brand, just wondering what is at play as I really resent their outrageous pricing and dumbed down marketing. Thanks in advance of any thoughts.
