Cable burn in

Qobuz (and I imagine most others) uses lossless compression and high quality streamers use buffering… so the file received will be the same. Obviously, from then on… it is all streamer dependent.

I think variable compression would imply active software on both sides, broadcast and receive. More importantly I think it would imply the compression was not lossless and to make a dent in bandwidth you would need to be lossy. So I doubt it.

I find it hard to believe the claim that "changing a piece of wire" will not produced an improvement.

If it were at all true then all that's need is a thin fuse wire provided it can handle the current. A bit like claiming digital is just 0's and 1's and nothing else matters.

Take speaker cable for example. All frequencies need to be transmitted equally without any timing changes and transients need to arrive at the speaker without change. Hmm, I'm wondering it house mains wire would be suitable. I think not.

 

Burn in, as a pattern..tends to go:

an initially dirty upper mid range glare and a subtle mono-ish effect,

then down to cleaner stereo but muted/darker/soft,

then slowly back up to cleaner, more evenly balanced dynamic stereo.

This, over a 100 hr period of playing a new cable, or component - with line level signals.

Do your research, this topic has been beaten to death for ever. The only rule of thumb.., Companies will charge whatever the market will bare. There are mechanical facts, there is a lot of BS with plenty a blow-hard. In short a person has to believe their own musical hearing.

Yes mains wire would work for speakers.
One can try it themselves to verify it.

The wire’s conductor does not know, or predict the frequencies… and it just lets the electrical field do its thing, thereby just pushing along the electrons... or not. The electric field propagates along largely irrespective of the impedance and current.

That electric field is not a timing and transcients thing. For all intents and purposes it runs at the speed of light, or some fraction thereof.

Is the OP using Qobuz or something similar?
Do they all work the same, or are some of the services lossy?
And if so, which ones are lossy or not lossy?
