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

I must be really really stupid not to understand much of these past several posts. I would hope the people commenting in such a technically proficient way would recognize that most readers have no clue what they’re saying.

There in lies a huge challenge, very very technical issues confounded buy those who don’t explain themselves very well. Very unfortunate as what they say is of value but lacks clarity.

They exhibit tremendous effort to achieve improved Sonic Quality I hope, and yet it has limited value to me because I am really really stupid I guess.

The marketing of these products can be horrible as the manufacturers don’t really do much to improve an understanding of technical information. Most dealers don’t understand all this. There have been noted exceptions along the way but still it is not explained very well.

I just installed a dedicated circuit for my system.  I installed 10 awg solid copper.  Although 10 awg supports up to 30amp, I used a 20amp breaker.  More than I need.  I also installed a 240V circuit.  I needed it since I bought a European amp that only uses 240V.  But I'm glad to have it for any future amps as doubling the voltage cuts the current in half for the same power.  This makes your amp feel like it is just sitting next to the power plant with a huge cord.  I too highly recommend running your amp at 240volts instead of 120 if possible.

To install 240V circuit the marginal cost increase compared to the 120V circuit is not much.  An extra breaker (perhaps $10) and 3 conductor vs 2 conductor wire, and then a slightly more expensive outlet.  the main cost of the circuit is all the labor and work inside the wall and cutting wallboard and replacing it.  All of that doesn't change when you install the 240V circuit with your 120V circuit.

Doubling the diameter of a wire increases cross sectional area, and approximate power carrying capability, 4 times, not 2.

The power delivered to the speaker is almost irrelevant to the power the amp needs, especially for class A.  Not sure why that discussion broke out.  My class A 35 WPC amp, that I run at about 1 wpc 99% of the time, uses 400 wpc, either at idle or at max volume.

I reference people back to page one to the post I made with a quote from the AR user manual where Audio Research requires a 20 amp, 12 awg circuit for a 75 wpc class AB tube amp.  I know many of you don't believe it can be true unless you hear it from an OEM so it is there in black and white.  I copied and pasted it.

I have yet to hear a conditioner that didnt take away as much as it gave. Far better to start with dedicated lines properly done and then experiment.

U think you are right...

By definition electronic engineering is about trade-off craftmanship...

In some case a conditioner is postive addition in some other case negative... And with the same gear it can also change in time if we change other factors in mechanical, electrical and acoustical working dimensions...

Your system? It would be good if put photos of your system on line under your user ID. Your experience? What components and power components have you tested?
