Prioritizing Power Cable Upgrades by System Component.

once again I'm going to disagree with a lot of members here but there are members here who agree with me.  Some are actually on the other side of my belief here.   I will say that I've got a much better understanding of the phsics behind electricity than just about everyone here.  But a lot of people say that there are many things in audio that are not explainable by physics and you just have to trust your ears.  I'm more a science guy.  The beauty is that everyone makes their own decision.

I would never install an amp without an upgraded power cable.  Many amps now don't come with a power cable because the throwaway cable isn't appropriate.  (I have a new amp on order and the literature says that.)  But you can buy a cable that will get you 99% on ebay for $50.  

Other components probably aren't going to benefit from an upgraded cable because they do not have spikes in their power damand.

@imaninatural  Yes power amp first.  Then I would make sure all my other cords are at least 14 gauge.  A name brand (Tripp lite) 14 ga power cord on Amazon is $11.  So in my system the DAC is the most important component sound wise.   My system generally only had 3 components in the signal path and one is digital so dont really affected by power cord:  streamer, DAC, integrated amp.  So on both my amp and DAC I have a nice power cord with good copper wire and good conductors.  I"m planning to make a new cord soon with braided 10 awg quality wire braided  and shielded. The shield is more to protect the signal cables in the vicinity.  But I'm saying this knowing that others strongly disagree with me.  Listen to both halves of the discussion. 

I really don't know what kind of power supply is in a turntable now so someone else will hae to discuss that. 

Oh yeah--powered speakers.  Give them a 10 awg power cord too.  Especially subwoofers.  they need lots of power.
