Need help ...

You have a good system. Your best bet for improvements are room treatments and cables.

thank you very much to every one give me suggestions. ....now i think i should sell MC C50 and looking Pass labs xp30 0r xp20. these speaker cable i’m using MIT cables and XLR shunyata connector and i’m thinking to placing some panel to reflex the sound it will help better sound right !

The Oppo is fine choice for background music or movies, nothing more.  With it as your source the rest of your equipment is way overkill.    

tanlv702,

Relax, Take a look at my system; similar to yours. Use Pass and MIT. Have had Wilson in past. I am still using a 26-27 yrs old CDP. Only thinking off replacing it due to on off has become unreliable.
I am a vinyl guy, so no hurry to replace it.
As others have suggested; Take your time. Get to know the equipment you have. There will always be better/ newer equipment to have.
 I am a firm believer in treating your room. DEDICATED ROOM is Key component. At least area behind and sides of your Speakers.
Again, Speaker position 1st. Then room treatment. If you want everything Now; hire a professional to do it. But I think you would learn more just taking time to study, learn and do it yourself over time. New digs can change things and you would need to start over.
Plenty of resources out here.GIK acoustics,"Master handbook of acoustics " Are good places to start.

Speaker Angle and Speaker Pro apps on iPhone are a Big help and inexpensive in the scheme of things. Learn to listen, you must have a dealer nearby to have obtained the equipment you have. He should loan you equipment to audition before you buy any more. There are dealers that will send equipment to audition for shipping both ways. Where do you live? I am sure someone on this site would help you. Post pics of your system; that will help us give you further advice.

Best Wishes; Enjoy the Journey
