What was the first power cable that you noticed a difference in the sound?


I have bought six or seven different power cords, none over $500 and have noticed little or no change in the sound of my system. All the cables are 12 gauge or bigger.  Without talking about cables made with unobtainium, where did you start hear a difference.
 

Thanks.

@panzrwagn  this video reports that this mastering studio gained 10dB of SnR with a wholesale (pre/post) swap of Shunyata products

 

 

First time I've seen a measurable figure shown...

@panzrwagn  right, I'm not saying it was apples to apples with the OP's question, but impressive a/b considering they likely weren't using zip-wire from Bestbuy  before the swap.

When my system was more basic (Parasound pushing B&W 6xx, or QSC ProAmps pushing Maggie 2.6, both pushed by a Marantz pre/pro and a Bryston pre/pro in swaps) I used Bluejeans cable (nearly 20 yrs ago I bought belden+carare setups from them) and off the shelf IEC power cables.  Amp swaps and pre/pro swaps made a difference. Cables... well, I tried swapping friends higher end cables vs. my bluejeans and I couldn't  hear a difference at the time.   Did I hear a difference moving to BJ vs. the translucent 16ga zip speaker wire and $2.00 RCAs, yup, but not between 2 "upgraded cables" since the rest of my system was what it was. 

I'm now running a BAK tube preamp and a Purifi powered amp (soon to be monoblock Purifi amps) pushing Tekton speakers and I can definitely hear the difference between 2  well regarded sub $1k DACs...  hmm, so things are getting more revealing.

Last month, I got a Puritan PSM156 and think my system sounds better with it, than without.  

As my system gets a lower noise floor, a larger SnR and more resolution, I "fear" I'll finally be able to hear differences in "real" cables... we'll see.  I run Mogami XLRs and speaker cables now... but a 'hifi brand's' black friday sale had me buy a few new ones to try, so holiday season listening should be fun.
