Paul Speltz Anticables PC did it for me. Being a disbeliever for many years I finally tried a pair (with a full refund guarantee). One in my DAC and one in my amp. The improvement was immediate and very obvious. I was shocked at the benefits. I've tried many others since, many of them much more expensive but keep going back the the very reasonably priced Anticables.
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.
