DISCUSSION: "It only comes out at night". Does anyone else have this experience!?

Certainly if you just had a fight with your wife… that preconditioning will have an impact. This kind of stuff can be relevant. But I have honed my listening skills for fifty years. I can over time differentiating conditioning from real sonic differences. Also, one of my pursuits as been philosophy with an emphasis on developmental and cognitive psychology… so I am familiar with stuff that influences perception. I detected this quiet time decades ago.

Most homes are measurably quieter, no trucks and cars creating mini seismic events, quiet power grid. I don’t drink scotch any more and am retired so, Sunday nights are not less stressful. No psychology required. Even when I comes down Sunday night and do not turn on my system the quiet is palpable.

@jhills “During the day, I have to strain to hear the ticking of any of our clocks. Setting on my audio sofa, at night (If I listen for) I can clearly hear the distinct and unique ticking of nearly every clock in the house”…

Yes, excellent point. Most are so immune to all the subtle background noise… your observation is exactly what it takes to be aware of all the components of the ambient room noise floor. When coupled with a quieter power grid you get the best time to listen. 

My system sounds best late at night, Sunday night in particular. I have noticed this for decades in different states. I am sure it is a quieter power grid. While I have a good quality power conditioner… the noise floor still drops late at night.
