I have a DCS Vivaldi stack, so in my view that allows me to hear differences of cables very clearly. It is apparent that Upsampler/clock/Dac need a VERY LIGHT TOUCH cable for best results .. so for source kit I would recommend such, but beyond that it is I am afraid an expensive matter of trail and error as to which gives best, according to the rest of your kit and ears. Probably a clock is most sensitive to cables of any type
Help selecting a power cord.
All my gear has the factory supplied power cords I’m ready to try 1 aftermarket power cable as a test. So what brand power cable should it be and what device gets it first? Tube pre? Tube main? D/A? CD transport? Roon Nucleus? Subs? GE Trefs?? Turntable? Oppo 103? Which piece of my gear should be most affected by the improved power cord?? I look forward to the responses and will likely choose the cord that has the most recommendations.
