Best speaker cable for audio physic padua speakers

Cables are not the answer. What amp are you using?

try ART/Yamamura cables, many people were using the AP speakers with these...also MF from stereophile...

I am using:
Cary 303/300 Cd player
Cary SLP 98L Preamp
Pass Labs x250
Taralabs air 1 ICs

Speaker cable are vary brand. All give beautyful sound on Mid and High range. But there is no energy on the bass.

Speaker cables would hardly give you an added amount of bass. It may make it more clearly defined, which in turn might lead to either a tighter perceived sound in the lower end. However, it's not going to magically give you that extra extension you want. All depends on a variety of factors, not the least of which includes the room your system is in (which I suspect might be it).

BTW, I run a pair of AP Tempo IIIs and they can be a bit shy on the lower end. That's because my room is fairly large and it's on a suspension floor.

Try Transparent cables (Super or Ultra with mm-technology). I used to have same kind of "problem" with AP Virgos few years back, but Transparent ultra speaker cables changed everything. They were great combination.
