Do speakers take time to warm up?
Speaker coil resistance can easily change by 10% or more after warm up.  It will affect crossover design and I'm very surprised,  that people ignore it, discussing "crossover charging" instead.  Also, to people who cannot hear the difference - you... 
Do speakers take time to warm up?
My mid-range and tweeters have ferrofluid.  I suspect that warm or hot ferrofluid behaves differently than cold ferrofluid.  Also hot speaker coils have higher resistance.  For copper it would be 4% for every 10degC.  Drop in power is negligible, ...

Slowly moving electrons represent electric current at DC. Electric current is amount of electric charge passing, per second. For the current to be 1 ampere electric charge of 1 coulomb (6.242 × 10^18 electrons) has to drift for 1 second (thru the ...

So the speed of the electric charge flow in a circuit is dependent on the connected load. The greater the load the faster the speed of the electric charge flows through the circuit. The speed of the electric charge is the same speed as the electro... 
Looking for Linear Power Supply for my Mytek Brooklyn DAC. Suggestions?
The problem with switching power supplies is that they vary from extremely quiet (all Rowland and Benchmark products) to extremely noisy and cheap (computers).   Switching power supplies are line and load regulated, work over wide voltage range an...

Jim, Electric current is a flow of electric charge. Electric current produces magnetic field around the wire. Any change in amount or direction of electric charge produces a change in direction and amount of magnetic flux around the wire. Change i... 
Anyone with tinnitus or hearing loss who is into "high-end" audio?
I completely lost hearing in the right ear 2 years ago (most likely virus). I went thru different treatments, that did nothing to my hearing but improved greatly my eyesight (not kidding). Life is funny, isn’t it? Loss of hearing brings white nois... 
MAC BOOK OR STREAMER ?
computers are inherently "noisy" and not built specifically to handle just musicBecause of that I decided to break connection between computer and audio system by WiFi.  That way nothing on computer side matters (playback program, computer speed, ...

An audio signal is purely a varying electrical voltage & current, just that . Nothing more.Let me start simplifying it:INDIAN SEE EAGLE OVER RABBIT  (instead of Ohm Law I=E/R)  ;)

Is that the reason, say, a Teflon dielectric, insulation, will cause ICs to sound better than cheap PVC insulation? Capacitance between plates is proportional to overlapping area and relative permittivity while inversely proportional to distance. ...

I would like to add, that it is as far as I can understand it and, of course, I can be wrong  (I was wrong once in 1964)  :)  
Simple question, or is it...
Electric charge moves together with electromagnetic wave at fraction of the speed of light in vacuum, dependent on dielectric (60-70%).What moves slowly in the wire is electron (drift velocity) - practically standing still at the audio frequencies... 
What the heck do these terms mean?
Dry, wet, organic, musical - it reminds me color selection in a movie:https://www.youtube.com/watch?v=s33ScN4D-HU
