powercords

Many years ago (and I'm giving my age away here), before specialist power cords were widely available a cheap upgrade here in the UK, was to use a 13 amp kettle flex. Much better than the standard offering, provided you could cope with the standard 3ft length. I got hold of some brown ones which were a nice match to Meridian 101/105's.

In my main system, I do hear an improvement with good upgraded power cords however I hear much greater improvement on all my other components.

Hello,
I have tested power cords and ended up with Nordost Blue Heaven on all the major components using IEC connections. I should replace the hardwired one in my TT like MC said he did. This might not be feasible since I have never done Something like that before. Bottom line is the question should not be does it make a difference, but what is recommended with my equipment setup. The first two components I tried an upgraded power cord on was my Denon receiver and Denon DVD player. On both Components, which were tested separately, It made a huge difference. Enough of a difference to spend over $300 on each of those components. The reason they give you the basic stuff with expensive equipment is because they know you are going to replace it. The second reason is adding cost to the components. Some things just need a basic upgrade and a thick gauge wire like with a lot of subwoofers. Other things like your streamer, disc player, or as I learned just now, the TT need it even more. Maybe just for the shielding alone to protect other things. Ask not what your stereo can do for you, but what you can do for your stereo!
 Like which power cable do you recommend for my setup?

I don’t know if anyone mentioned it already but given that wire directionality is important for fuses in AC circuits doesn’t it stand to reason that wire directionality comes into play for power cords, too? Just curious.

Is there some risk that the mfr will misplace the power plug and component input opposite the cord wire directionality? If so, how would one determine that this has occurred?
