Just to be clear the ifi product uses an electrical circuit to reduce noise, the QSAs is just a plain connector with nothing physically different than a standard connector. The magic is in the treatment QSA does to the connector. I've heard they expose them to large doses of simulated cosmic radiation, and/or conventional radiation for increasing periods of time, the more time the higher the price. But this is just speculation, nothing public is known what they are doing. The cost of equipment and power consumption generating these types of fields can be quite large, as a way of explaining the cost.
Many many people swear the positive changes using them are real, and that is good enough for me. Though I doubt I'd pay money for them myself.
