Congratulations Ernewald! You live in a area where the electricity is as pure and clear as the skies. (no sarcasm intended) I agree with Tireguy, if there are no differences heard with upgraded PCs, why use them. I am also a fan of Cords and Conditioners. I will add one more unit to the mix, since I have not heard anyone mention. I currently use the Tice Solo Power Conditioner and the Tice Solo Enhancer.
The Tice Enhancer has no filters nor can it remove anomalies or spikes and surges from the power. What it improves, is the depth and dimension of your soundstage. You have heard of cryogenics I'm sure, where a material gets frozen. Tice uses the complete opposite technology. Tice uses High Current Electricity to treat thier component materials.
I have my DAC, DIP, Transport, and Power Conditioner plugged into the Enhancer. My Amps are plugged into the Power Conditioner. I have tried many combos and this worked the best on my system.
I mention this passive unit as a tweak instead of Power Conditioners that you may not have a need for.
