California officials are calling foul on a company hosting man vs. robot cage fights in the state. Robot Entertainment Kombat hosted what it called the “world’s first human-robot fight” in San Francisco last month, shocking the internet.

		<description><![CDATA[Many audiophiles leave their amplifiers running all day because they believe switching them on and off causes more damage over time.

For owners who have spent thousands on their equipment, it&#039;s an understandable precaution. Nobody wants to shorten the life of an expensive amplifier just by using its power switch.

And the concern isn&#039;t entirely imaginary. Repeated power cycles introduce stresses that engineers have studied for decades.

But there&#039;s a reason amplifier manufacturers still disagree about the best approach. The technical documents from the companies supplying their internal parts reveal another side of the debate, one that rarely comes up when audiophiles discuss whether to leave their equipment running.

		<description><![CDATA[I have to laugh at at some of the ridiculous claims that are made concerning power cables and other accessories. If you like it and don’t mind wasting the money, go for it. 
The power cable’s job is nothing more than to make the connection to the power grid. If you have noisy power, add a filter. If you purchased high end gear, hopefully the designer did a good job engineering a good power supply with proper filtering. What little filtering could be accomplished with power cable  material choices and geometry is nothing compared to the Pi filters or active filters in high quality audio gear. 
A fool is soon parted with his money.]]></description>

		<description><![CDATA[The shortage of CD drives has already forced Naim to drop the drive from one of its players and pushed PS Audio out of the SACD transport market. But Chinese audio brands somehow keep launching new machines anyway, even as they face the same broader decline in optical-drive production.

its explanation seems to lie in what these companies are willing to build around, and it&#039;s looking like Chinese brands have outsmarted their Western rivals once again.

And it could decide which CD players remain affordable, repairable, and even available a few years from now.

		<description><![CDATA[That is true for virtually every standard scenario: at audio frequencies (20 Hz to 20 kHz), a cable&#039;s physical length is so negligible compared to the electrical wavelength that transmission line effects—like standing waves, impedance matching, and voltage reflections—do not govern signal behavior. 
For virtually all real-world audio installations—whether studio interconnects, 100-foot live stage snakes, or home Hi-Fi speaker wires—cables behave strictly as lumped-element circuits. High-frequency rolloff in long runs is driven by simple RC low-pass filtering (output impedance of the driver working against total cable capacitance), not impedance mismatches or signal reflections. 
​The only niche exceptions where transmission line math enters the audio domain are digital audio connections carrying high-frequency square waves (such as AES3 or S/PDIF at 3 to 6 MHz, where 110  or 75 ohms characteristic impedance actually matters) or ultra-long telecom runs spanning many miles. For analog audio, lumped parameter models tell the entire real-world story.]]></description>

		<description><![CDATA[BELOW TAKEN DIRECT FROM Headphonesty:

Speaker cables are one of those upgrades people can argue about forever. Someone swaps copper for silver and swears the whole system opened up. Someone else hears absolutely nothing and wonders what everyone is paying for.

Then a YouTuber decided to take that argument somewhere ridiculous. He built speaker cables using liquid mercury, knowing full well it is a much worse conductor than copper, and expected the music to give him away almost immediately. 

What happened once he started listening was not nearly as simple as that. And the really interesting part comes after the listening, because the numbers from the finished cable tell a very different story from what “57 times worse” makes you picture. 

That is where this stops being just a strange mercury experiment and starts getting awkward for anyone who has ever paid more because one conductor was supposed to be better than another. Especially once older blind cable tests enter the picture.
