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.

The Padua will produce fantastic, tight bass...they are very capable at the bottom end. The trick is in the placement. If you don't have the luxury (room) of following the Audio Physic technique, experiment keeping the speakers wider apart...you will magically see the bass show up! These speakers are fantastic...

Maybe you should give MIT a try. I once bought Magnum3 sc to combine with B&W 805 Sig monitors and these MIT's 'produced' a wonderful bass (my amp at that time was Plinius SA201 solid state. I had to sell them when I moved on to Kharma floorstanders (too much bass).
