Why do I need power management if I have a great power cord?

”Why do I need clean water if I have good quality copper pipes? ”

Good one.

I take a break from listening to music when the leaf blowers get near. Hopefully they will be replaced by electric soon… mine is.

From Audio Research VT80SE manual. This manufacturer gets it:

"A.C. Power Connection It is important that the VT80 SE be connected via its supplied 20 amp IEC 12-gauge power cord to a secure, dedicated A.C. power receptacle. Never connect to convenience power receptacles on other equipment. Only use the power switch on the front of the VT80 SE for On/Off control of the amplifier, or the 12V start-up trigger for remote installations. The AC power source for the VT80 SE amplifier should be capable of supplying 10 amperes for 100 or 120 volt units, or 5 amperes for 220 or 240 volt units. For the very best performance on 100 or 120 volt circuits, the VT80 SE should be connected to its own AC power circuit branch, protected by a 15 amp breaker. The preamplifier and other audio equipment should be connected to a different power circuit and breaker. "

Note that it requires 10 amps at 120V.  That is 1200 Watts.  Nameplate wattage for this amp is 200 watts at low power.  This is the concept that many "audiophiles" reject.

It’s been fun and interesting reading all these responses this morning. I didn’t mean to hijack this thread from the author. I have a question for those of you out there that believe that the majority of these products make a difference. Let’s use transparent cable as an example. Their interconnects range in price from a few hundred dollars to $37,000 for a pair. What makes them worth $37,000 a pair? Just to give a reference of what $37,000 will buy, here is a list of the top 10 cars that $37,000 will get you. 

10 Best Luxury Cars Under $35,000

• 2022 Buick Encore GX.. 
• 2022 Cadillac CT4. ... 
• 2022 Acura ILX. ... 
• 2022 Mini Countryman. ... 
• 2022 Buick Envision. ... 
• 2022 BMW X2. ... 
• 2022 Lexus UX. ... 
• 2022 Mercedes-Benz A-Class.

I know I know this is America you can charge whatever you want blah blah blah. Don’t you think that this kind of makes people wonder what kind of voodoo is making two pieces of wire worth $37,000. Do you think it helps or hurts the argument that something weird is going on?

Having a nice setup and Tektons WITHOUT fancy cables,conditioner and fuses doesn’t sit well on an audio forum.

The OP’S questions will never be answered from either side.

Fascinating how no one discusses how proper shielding will protect from all the Radio frequency related noises, within all the comments herein, that are generated after the electrons depart from the wall. It’s all very simple why does everyone overthink this problem?

Further no one seems to discuss measuring the interference that occurs before and after Power conditioning. To me this would be a huge selling point yeah no one talks about it. And what about restricted versus unrestricted electron flow that many conditioners do or don’t do. Thereby explaining why amps should go direct to wall unless power management device is unrestricted.
