Power Cables


Is it necessary to use the same brand and model of power cables for the amp and pre-amp? Any thoughts about mixing and matching? I know it all comes down to how they sound, but would love to hear your inputs or tips to guide me in the selection.

The standard power cable provided by the maunfacturer is not capable of responding to the immense demands of tranient signals. More advanced designs allow the conveyance of enough power in a timely manner such that an amp can perform up to its full potential and reproduce those transients more faithfully.
 
I loathe to ask, but (a) what part --specifically-- inherent to the "advanced" power cable enables it to allow more power from the station / to the pole / over the lines / into your home through the walls after going through its own short run of wire? And (b) what part of the PSU system within the component senses and allows more current than what it is specified to engage .. a timely conveyance of it, as you say, to increase audio transients? Finally (c) what makes this wire magic so expensive that it is not within the cost/benefit analysis parameters of the manufacturers to include it with their mid to higher priced products if the difference is so easily heard? Thank you.
Sincere apologies for keeping this one going, but so many posters in cable threads are talking entirely through something other than their mouth when they make claims about "demanding" audio transients requiring something from a power cable when anyone with amplifier 101 knows the mains are decoupled from the circuit practically the entire time thanks to capacitors.
Great. Now that you've written all of that, explain to us how this makes a single iota of difference when in an amplifier's linear power supply the current through the mains is only directly in use 5 to 10% of the time since the power supply system's inherent design is to fill capacitors that provide smoothed and constant direct current for the supply rails that ultimately amplify the signal. Unless your contention is that the current provided by a scant meter or less of cable has somehow conditioned the wall current in such a way for storage in the system's res capacitor(s) that it is improved in some way that impacts what exits the system to be reproduced by cones. That's one magic sonic loogey you got there!
Yes, that's how it works. I'll provide a link. If an amplifier is correctly designed, "sagging capacitors" amounts to a cable marketing blurb. If you think any substantial amount of juice for your volume control is coming directly from the cable you paid a lot of $ for then you're not following the design topology and you're listening to music with your wallet.
