Power cable upgrade for ARC

Wondering if you typically get better results upgrading the power cabling on an ARC preamp or the amp. I don't have the budget to do great cords for both at the moment. I understand trial and error are the best way to find out, but wondering in general terms which piece is more sensitive to power cabling? Both pieces have dedicated A/C lines currently LS17 (15amp) and Ref 110 (20amp) and both are using stock A/C cables directly into dedicated outlets with no power conditioning. Though I do run a PS Audio UPC200 conditioner for my Bryston BDP-1 and BDA-1 digital stuff (also on separate circuit).

Yes I think we misunderstood each other.

Both of my ARC pieces have detachable AC cables. The LS17 uses a typical 15 amp IEC plug and the Ref 110 uses a 20 amp square plug type.

Any thoughts or experience on which one a cable upgrade is more beneficial to? (speaking in general terms of course).

This would be much easier if both took the same type connecter as I could just try swapping them. Being that they don't, I will need to go through a bit more trouble or buy two of the same cables with different connectors to experiment, if my dealer even has one of each in stock as many times the cables will need to be special ordered (understandable given the current climate, but it doesn't help my cause). I would like to avoid this if at all possible... Trying to avoid the hassle and asking my dealer to accept a return if not totally necessary.

Thank you for all the feedback. After speaking with ARC, I have opted to upgrade the power cable first on my Ref 110 power amp. I bought an RGPC High Tension Wire and am enjoying it - only difference I find is that the sound is overall, moderately faster, no tonal changes, which to me is a good thing. In due time, I will also upgrade the cable to my LS17SE.
