Animation speed without losing quality?

[caskal 120]

Hello all, I made an animation with a solver but it runs too fast, I tried time shift sop but kinda loses quality, what I want is a slower animation but without losing frames, I'm new to houdini, tried with chops but I know im doing something wrong (ideally I would like to drive the animation with sound, but for now lets just slow down the thing)

Here is the animation

I want the lines go slower but without taking out keyframes, slow and smooth, any suggestions?

Thanks!
