Does a Good 20 amp cable Make a Difference

Hello everyone,

Since I purchaced a shunyata Power filter over a year ago.I noticed that after I upgraded to better a/c
cables for my sources I noticed a remarkable improvement in my overall sound.Indeed it can be a long and ardous journey in the quest to find great power cable that will best suit your setup,and bring out the most in every manner possible! Thankfully Ive been quite fotunate in not having to test too many cords in finding the right one!

Now my query over bettering my cables for my components,is the one for the power filter itself! Im presently using
a Shunyata Diamondback 20 amp a/c cable for this purpose alone.I gather IMHO Its more or less at $200.00 something dollars its probably one of their entry level cable.

Now seeing im presently using a/c cables that are in the $400 $500 $600+ range.Would it not make sense to go equally for a great 20 amp a/c cable for the the power filter?

And could this upgrade bring all the other cabling on the filter brought into better perspective.and would the diff
erence be an appreciable one?
