Hi current or source power cable

Source cable. They are heavily isolated… noise reduction. Power are very heavy gauge for the high current of amplifiers. DACs require relatively small current.

However, I recommend a good one. I use Transparent. It will depend on your equipment. I was recommended by Shunyata a relatively inexpensive NR and it really did nothing. The Transparent had a very positive improvement on my DAC. But as always, different systems react differently.

I tested 3 power cords on my Aurender N200 streamer. Furutech FP-S55n (10awg), FP-S032n (12awg) and AQ Tornado High Current. I preferred the heavier gauge cables. Currently using the AQ Tornado HC.

AQ Makes “source” version of Tornado and Hurricane. I never tried those. But to @ghdprentice point, it’s worth a shot because different components will react differently to the same power cord. 

The external power supply does not need more power.  If anything less.
