Can streamed Music sound better on a Sunday?

In my experience, sound quality can vary from day to day.  It may be the amount of noise in your electricity, the noise level in your home, your frame of mind on a given day, or many other factors.

Whatever does it, enjoy!

I agree that SQ is elecricity dependant. It is however not a new finding, there is a reason that power conditioners are used in hifi setups. What is interesting though is that using my own solar produced electricity incl. battery stored electricity brings a significant improvement. 

Mine always sounds the same, maybe you need to look at your system.
Bits are just Bits nothing more.

So my question is can audio that I stream on a Sunday sound better than the same music during the week? Is it possible that you get less bandwidth when things are busy during the week versus when there’s less traffic on a Sunday?

That's an interesting question. Bandwidth does have a huge impact on quality. HD was originally intended to be High Definition- one channel of ultra high quality audio and video. Until the suits figured out they could stuff 500 channels of I Love Lucy and weather reports into the same pipe as just one HD movie. Streamers could be doing something like that. 

But, I rather doubt that is the reason. Because they would need some reason to be going back and forth. Bandwidth costs, they aren't streaming for charity. More likely its just you are noticing what others have mentioned, its the power.

There's a simple enough test. You already hear the difference streaming. That could be bandwidth. Now try CD, or records. If those also sound better, well then its not bandwidth.

Bandwidth will play no part in this, a high definition film only needs 3 Meg a second to stream and the requirements for music is much lower.
So this is not a consideration unless you are stuck in the past and still using a modem on dialup.

Not sure where you people get these ideas from but they are not based on facts..

Streaming music doesn’t require much bandwidth—almost all current internet speeds are more than fast enough to keep your tunes rolling. In most cases, 500 Kbps (0.5 Mbps) is enough speed; you’ll need more speed for multiple streams.
