Opinions on differing power cable for amp and preamp

@kingbr 
I see you get my point. I had to mention this because it was the most obvious change using a cable that I have ever heard and unfortunately it was negative. 
Maybe you can do like I plan to when it's time for me to do power cables
(Im saving that for last, in the mean time I have Pangea 14SE's throughout which I've had since another system)
which is try power cables from companies with trial periods.
After my experience with the Verastarr cable I tried, I would hate to get stuck with an expensive cable that hurts my system.
No disrespect to Verastarr just a synergy issue.

Thanks @rushfan71, of course I get your point us Rush fans truly speak the same language:)

While I use a mix of Nordost Valhalla and Acoustic Revive reference power cables, getting clean power to the system involves much more than power cables: a separate spur, power conditioning through either a balanced transformer or passive conditioning (Acoustic Revive, Furutech) as well as grounding support (again Acoustic Revive RGC-24, Akiko Audio) as well as proper EMI/RFI filtering of the individual units‘ power supplies. The power chord is but one component of the system and the aim should be neutrality rather than a specific sound characteristic.
