If I left the room for a half hour and came back, would I know if it was plugged in or not.
I think that you would know.
Well, if it remained plugged in, you would not know. That is, until you returned and it was not plugged in.
When you degrade the sound quality, even just a bit, it is more easily noticeable than when you improve the sound quality just a bit.
Approximately 15 years ago, my local high-end store loaned my a Shunyata Research Python power cord. The owner told me to use it with my CD player. I was not a believer in such cords. But it was simple enough to try.
I plugged it in, and played a song. I was expecting no improvement or perhaps I would have to strain my ears to hear a difference. So the first song was playing, and that is what happened. I noticed nothing, but was not 100% certain. So a few more songs played, and I realized that I was in the zone. That is when it hit me, that that power cord was the reason.
To be sure, I put back my original power cord. The magic was gone. I immediately heard the sound degradation. I put the Shunyata power cord back, and life was good, again.
Based on my experience with that power cord, I believe that you would immediately notice if your Venom v16 was absent.
