Power Cord Recommendation

I have had a bunch of modestly-priced PC over the years, including several from Pangea and Signal Cable in my fairly high-end system, and none of them made a wit's worth of improvement in the sound of my system.  However, recently I bought a Shunyata Venon 3 PC for $100 and a Silnote PC for $120 and both were a very worthy improvement in the sound of my system.  I also bought the Cerious Technologies Graphene Express PC for $350 and it is even better than the Shunyata and Silnote PC's.  I will say that with all three PC in mentioned that the improvement in sound was immediately apparent when they were swapped into my rig...  the improvement was clear as a bell from the get-go.  I scoffed at the notion of PC for years, but I am now a complete devotee.  All these PC can be auditioned with 30-day return policy.   

Power cords are power cords.  They do not transmit audio information.  Do your research and do waste good money on bad information.

Do your research, here is a great explanation of how little influence a power cord has on how your system sounds:

I have limited experience with trying different cables but I can tell you that I have had several Richard Gray Power Cables and never was sure they made a noticeable improvement in sound.I decided to take the plunge and invest in 2 Shunyata Python 20 amp cables for my ARC amp and pre.I was sold on them after 15 min of listening.They really got rid of that low level noise that I never knew was there.I was hearing things in the music that I never before.There are literally hundreds of  cable companies out there and many make fine cables but I have only tried 2.
