Right match

Can you describe “sound is horrible” in terms of ‘in what way it sounded?’
Or what was wrong with the sound?

Or plug an iPhone or iPad into and RCA adapter and see if that sounds good.
Just not on a phono input, use an Aux, or some other line level.

Also I want to add this only have 6 hours of break in time but I heard some people said that power smp and preamp don't need break in time like speakers that need around 500 hours.Can that be the issue is to soon just 6 hours of burn in time

No…
it should not sound bad by default at the start.
Something is jacked up.
Pre or, cables,

I'm going to give it a chance and play it around 60 hours to see only have 6

Usually this stuff goes from great to better.
Not from woeful to great.

And some of the “great to better” may also be psychological.
Most of the time I find it sounds a bit different when I swap gear in, but I am never sure if it really sounds different, or if I just want it to.
At best, it has been subtle.

Maybe some gear would be only be good to great, but seldom woeful to great.

Something is jacked up.
I usually start with this: 

It should be pretty good just from an iPhone or iPad. It should not sound unlistenable, and provides a decent way to test out the inputs without ground loops.
