No snake oil - good ones make a difference - here's why...
NOTE: For brevity I am going to bypass the power requirements of the electronic circuits and the many factors that influence circuit design etc.....mainly because I don't recall them from 40 years ago when I did have some understanding of them :-)))
So looking at the back-end of the amplifier - i.e. Speaker terminals...
The signal "sent" to a loudspeaker consists of a varying VOLTAGE (i.e. at the musical frequencies and various volume levels of instruments) - a very dynamic and complex signal
The "impedance" of the speaker governs the amount of CURRENT that is "drawn from the amp"
- impedance is like resistance, except...
- you have to factor in inductive and capacitive elements
- those vary with frequency - so impedance too is very dynamic!
- Current Drawn = voltage(which is dynamic) / impedance (which is very dynamic)
- net result - the frequencies in the music causes very dynamic variations in current "drawn from the amp"
- if you could see a waveform of the current delivered to the speaker it would resemble the musical waveform - sort of :-))
- So - POWER CONSUMED = CURRENT x VOLTS - all of which are directly related to the musical waveform and very dynamic
Now - at the wall outlet end of the amp -
The mains supply to all components is constant at 120v ac (I'm not debating power fluctuations here OK!)
Basically remembering that "POWER IN = POWER OUT"
- if POWER = CURRENT x VOLTS and the volts are constant @ 120v
- then CURRENT = POWER/120v
- if the power at the speaker terminals is dynamic (from above)
- then the CURRENT required from the mains supply will be dynamic also
- WHY? - because the voltage at the outlet is constant!
So, providing your house supply is sufficient, you can see that the mains supply current requirements are directly related to the musical frequencies and very dynamic and will have all the same requirements as interconnects and speaker cables - it needs good quality copper.
So what happens if the component cannot get the instantaneous current levels required?
- the component experiences an internal instantaneous voltage drop
- this seriously impacts the performance of the component across the board!
So we spend a lot of money on the best quality copper for speaker cables and interconnects, having low resistance/inductance/capacitance and quality connectors to get better transmission
- then a component manufacturer sticks a crappy 18 gauge mains cable in the box and we use it !
- but first we toss the crappy interconnect (that is about the same quality) - because that's not good enough!
- GO FIGURE!
SO - Doesn't the component also deserve a Mains Cable of similar quality as ALL other cables in our system?
- probably more so.
Only with good power cords can we hear the real differences further down the line!
So snake oil? - some cables market a lot of hype, when in fact it is pretty simple - look for...
- good quality copper
- some form of noise cancelling geometries or shielding
- good quality plugs/connectors
Yes - the supply fluctuates - cables won't help that
Yes - some amps may benefit from a cable that has some smoothing properties (verdict still out on this one)
Yes - silver cables are probably better than copper (verdict still out on this one)
And a million other claims.
Bottom line - a good cable like a Furutech (that's what I know works on my system) will provide sonic improvements
If it doesn't then the power cord is not your problem - look elsewhere!
