Power Cord recommendations for a First Watt SIT3

I would likely upgrade the power cord.  The cost of a 10 ga power cord is less than drinks with a friend.  I've seen power cords make a tremendous difference with smaller amps than this.

I don't own a pass amp. Can someone look at the information stamped on the sheath and post what gauge wire Pass uses in the power cord for this amp?

Any amp with an IEC power inlet would give you a reason to experiment. The supplied cords that come with the gear, are good to start off with. However, there is more to be gained in a upgrade, specifically the gauge, as mentioned above. For that amp, I would go a 12 gauge. 10 gauge sounds too wooly and tubby with this amp, imo. Although I build my own, there are many cable design companies with starting prices below $100, again as stated above. Read the reviews by customers / owners of these cables. You will find a sound that " lets more in ". I am yet to find a supplied power cord that could not be bettered. If you know what to listen for.....Enjoy, my best. MrD

My 1976 Mcintosh MC2100 has a non removable power cord. I love the sound but wonder what's missing?

What gauge is the stock cord supplied with the pass amp? If I’m not mistaking it’s a 14 gauge power cord and it is not bad. However, I have owned two Pass Labs amps and both benefitted from a power cord upgrade. 
I used Shunyata Taipan Alpha Helix with the X250.5 and had good results with Audience powerChord as well.
With the XA30.8 that I currently have all of the following power cords were an improvement over the stock cord: TWL Seven Plus, Acoustic Zen Krakatoa, Acoustic Zen Gargantua II, Furutech FP-S55N (currently on the amp).

FWIW I ended up keeping the Furutech on the amp and kept the TWL for preamp.

You won’t know until you try and hear it for yourself. The TWL cord comes up on used market once in a while, does not cost an arm and a leg and you can sell it and break even. Nothing to lose except keeping yourself wondering. 

It probably sounds good with the stock cord but wow if you can't hear the change in sound from different power cords you need a new hobby.  I'm always like and I'm out on that guys opinion forever when they say power cords or any cords don't make a difference to the sound, and chances are they are just talking without any experience.  The Sit 3 will definitely respond to different power cords.  On the cheaper end of the spectrum I like the Audio Envy power cord.
