Ever wondered why you sometimes have to wait months after an album's launch to get the music on vinyl? It's not necessarily because the label hates vinyl — in many cases, it's because the decades-old manufacturing process can't keep up with the format's resurgence. Relief may be in sight for turntable fans, though. Viryl Technologies is producing a pressing machine system, WarmTone, that should drag vinyl production into the modern era.
Much of WarmTone's improvement rests in its use of modern engineering. It's more reliable when producing the "pucks" that become records, makes it easier to switch out stampers (the negatives that press records) and sports a trimming/stacking system that can better handle large-scale production. Also, there's a raft of sensors -- the machine checks everything from pressure to temperature to timing, so companies will immediately know if something goes wrong.
Logically, the interface has been spruced up as well. Touchscreens help control the pressing machine on-site, and workers can check on the state of the machine from their computer or phone.

That isn't true. It has to do with the harmonics. IIRC, transistors driven to clipping have odd-order harmonics, and tubes have even-order harmonics, plus the transformers used in tube amps have a lot to do with the harmonic distortion.

Have a look at the waveforms on an oscilloscope.

one way to describe a square wave is an infinite series of odd harmonics...
