Advice needed on power cables, wall warts, conditioning, electrical outlet

You'll need to replace all the wiring in your home with 99.99999999% OFC, then do the same for the wiring from where ever it is that provides your house's power all the way to your house. Then replace the wiring in any component and speaker with the exact same wire since those manufacturers use the cheapest wiring they can to save money. Only then will you have the best sounding music possible.

@terry9 

you have about the only believable post on this subject. And since the isolation transformer provides a good low impedance supply, you see the better transient improvement. 
 

Power cords, unless they are thinner than your house romex, will NOT make an improvement.

Thank you. I sometimes feel a bit lonely when trying to help someone who genuinely wants to learn.

@terry9 

Thank you so much for your post, that's the kind of information that rewards hours and hours spent on audiophile's forums. I will definitely try an isolation transformer, never thought about that before:) 

Do you recommend any in particular?

Last thing, do you use to connect all your gears to it or just amp/preamp?

2. installed isolation transformer to run separate outlets at 20% of above cost

Using a VooDoo Electra power cord on my PS Audio BHK pre amp and a VooDoo Black Diamond power cord on my BHK250 power amp, I hear a significant improvement in everything over their stock power cords.  The Electra was plugged into my Denali 6000/S power conditioner; the Black Diamond plugged directly into a PS Audio wall receptacle.  I'm using a dedicated 20 amp circuit.  I also have a whole house surge protector in my electrical box.

Care to share the name of the isolation transformer? 

I'm considering a move to Cardas Clear Reflection power cords and interconnects.  I'd like to do some A/B testing using my VooDoo cables against their stock power cords with an isolation transformer in the mix.
