@westcoastaudiophile - You can borrow cables from the Cable Co., or borrow one or more from someone you may know and conduct your own tests. You didn't respond with details about your equipment, but maybe use the Audiogon virtual system search and find members who may have a similiar amp, DAC, transport, streamer , whatever and determine what power cables they are using that you can then trial and compare results with. No better way to determine if you will or won’t hear an SQ difference - good or bad- in your system than a hands on trial. No worries then about if others simply reported perceived purchase bias, no worries then about your pre-judged measurement bias clouding the issue , no worries about taking someone else’s blind test claim for granted etc. Your can put yourself in a position to make your own objective determination, and then you can make a definitive statement of the results in your system. Personal trial, highly recommended!
