porter port feedback

i recently ordered 2 porter ports..and am anxiously awaiting delivery/installation...id like to hear from those, will all levels of systems that have used these...any negatives? or is this just one of those "gotta haves" thxx
No negatives. Well worth their cost.
They work well for me too!
Best budget tweek you can find..And a great guy to deal with..
I'm happy with mine. They are very neutral and dynamic. Best bang for the buck in my system. Allow some time( a few days) to settle in for best sound.
youll be pleasantly surprised at the differance.More detail,bass extention.Its a got to have imho.
Excellent product. No need to spend more on an outlet.
Very impressed !
