Are the sonic differences we hear real or imaginary?

  1. I took the question differently than you Paul. My system changes in small ways without making any changes to the equipment or the wires. We have talked about AC power changes in a twenty four hour period, so maybe that’s it. Room temperature could a culprit. Who knows? My mood may make a difference but sometimes I hear a difference in my system for no explainable reason. Can you shed any light on this?

    1. Definitely, AC power has a great deal to contribute when it comes to changing sound during the day and night. It’s one reason we invented the Power Plants that fix it. Still, air density, mood plays a part as well. In my experience, if you build a solid foundation for the system including regenerated power you’ll reduce the chance for change dramatically.

  2. Is the reason you won’t try auditioning Ethernet cables because you’re afraid of the consequences of finding out that they actually make a difference? …. 🙂

    For two weeks I slipped an Audioquest Ethernet cable into my system for the run between the Cisco Ethernet switch and the Mac Mini in my listening room, and I have to report that it made a slight audible difference. For calibration purposes it was more of a difference than pushing the de-gauss button on my P10, but less of a difference than using the LAN Rover.

    Of course, it raises all sorts of questions that I can’t answer.

  3. One simple test which I use to evaluate speaker cables and analogue interconnects is to put one cable (the one I’m familiar with) on one channel and the other new cable on the other. The differences are readily apparent. No double blind testing needed, no switching.
    And I have not yet tested two analogue cables that were not in some way different to each other – sorry to any cable sceptics.

    I can’t figure out why no one else has thought of this. There is no chance of bias or placebo. No issues with delays in switching and bad acoustic memory. If you haven’t tried t, do so. You might find your assumptions being challenged!
