Well...I have had my iQSEs for almost a month now. One in SACD player, one in line stage and one in power amp. I don't claim to understand the "science" behind these devices. If I understand Bybee's explanation, the crystals in each iQSE condition the EM in the applied gear resulting in a more natural, organic sound.
There is a conversation on PS Audio's Power Forum about these. Paul McGowan who is an engineer/designer admits that he often doesn't understand the "science" behind Jack Bybee's offerings but in most of his experiences, his devices do what he claims for them.
So what do I hear? Rather than try to identify a typical audiophile characteristic, for me my listening experience is more involving ( I find myself putting down the laptop or magazine"), I listen longer finding new appreciation for long loved recordings. This increased level of listening involvement is consistent since installing the iQSEs.
If your involvement in audiophilia is dependent on scientific bases for what devices you employ in your system, then these are probably not for you. And that's fine.
For me, there are many experiences in life that occur around the world that seemingly transcend science. I plan to stay open to my ears and my body's reaction to what I hear. Science or not.
