@audphile1 , +1, Yes sir, no system , no market feedback, no posts started. It’s a wicked existence in the peanut gallery. As a financially limited mid-Fi guy even I have found an improvement in a power cable upgrade. Now truth be known for me it was about 1/3 of the time. My biggest change was adding a Shunyata Venom HC 20 amp cord to my Richard Gray power filter. This was in addition to a Hubble outlet upgrade, and it was very noticeable. What chaps my ass is that someone can make a lame blanket statement and impose it over and over. My apologies for not posting my frugal system.
