Ditto here too. Never heard of OP (or anyone else posting here) before I answered this thread. I bought my entry level Hemingway PC at retail from an authorized dealer and the speaker cables used from a fellow Audiogoner.

 

Man ...some of these posts are getting as bad as the snarking on CNN and Fox News casts......it is a great hobby have some fun. Now relative to the OP's post , I recently purchased a used Hemingway Creation power cord from an established and very well respected Audiogon member here who really enjoyed Hemingway cables. So I purchased the Hemingway Creation power cord from him and placed it in my system. I will say that in my system and will say that once again , that in my system the Hemingway Creation power cord had an immediate presence. A presence that seemed to be an addition or to an added extent an '' energy '' or '' sizzle '' to the sound. I was not prepared for this effect if you will. It was like to the treble got an added jolt of energy and what I thought was very odd was that the drummer's foot pedal / bass drum sound was front an center and very prominent which is not the usual case even in live music. I am not saying that it was bad thing but there is definite something going on with these cables in the way they are made and the materials used. I sold my HC cable to another Audigoner here who is using it in his all tube system as my system is all solid state Accuphase and absolutely loves it ! I personally did not understand or like that proposed excess energy that the Hemingway added to my systems sound. It is however and just my 2 cents a company and cable worth looking into. Stay well and safe these days …...

You implied that a few of us were in collusion by our comments showing interest

$$ power cables have no value, other than nice look / flexibility / Dr feel-good. All high end equipment I am aware of, supplied with the same pwr cables as used in the performance tests. I would love to hear about “blind test” results between $1000 and $5 power cables! Typical house wiring uses tiny wires, having x100 resistance than any power cables of hifi components. 

If high freq power noise bothers you, you need LPF or power conditioner. Easy way to fix is to add filter clamp to your cable.
