Which speakers to be ''in'' the music?

berner99 is giving you good advice

your english is fine

good luck have fun

Graham Audio LS 5/9 have beautiful rendition of instruments, piano, brass and especially violin sounds great, but it is male voices that really impress me, I was looking for a long time for speaker that could reproduce male voices in a satisfying way and I feel I found that with the 5/9, most speakers I feel do a good job with female voices, but I feel very few do good male voices, maybe because to me it sounds like 90% of the speaker market are thin sounding and very fatigued after longer listening sessions.
Spendor Classic line would be a good bet too, as would QLN.

Wide dispersion is a great way to maximize room interaction and is way more often as not a big mistake. I can't help thinking that what you are looking for is headphones but I think this is most likely a distortion of translation. 

Point source speakers such as you are listening to have miniature sound stages. They put you way back in the concert hall. Line source speakers give you a large soundstage and put you right up front which is what I think you mean.

There is one speaker in your price range that is a line source dipole which will meet your request beautifully and that is the Magneplanar 3.7i. This speaker may qualify as the single best value in all of Hi Fi dom. It has a few weaknesses which you should be aware of up front. They like power. They are an easy load but are just not very efficient. Tube amps will work fine but you will need 100 watts/ch. Even with a lot of power you can not expect them to hit the volume levels regular dynamic speakers do but they will go plenty loud enough for the music you like. They are not a good speaker for metal maniacs. They do not go super low down but few speakers do. If you want to shake the neighborhood you will need subwoofers. What bass is there is superbly defined and they give percussion a snap missing from most speakers. They have arguably the best tweeter ever made.

Most other speakers are just more of the same. When you listen to these you will know you are listening to very different loudspeakers. Listen to these first and you probably won't even bother listening to anything else so save them for last. Have fun and good luck!

I am not going to belabor others points above.  Yep.  

Check out Raidho.  They deliver a massive and immersive soundstage.  Even speakers as small as the X-1s assuming your room is setup correctly.  Scansonic does this as well, just not quite as effectively (same company).  I enjoy their stand-mounts with a subwoofer.  

Audiovector - has a rear firing tweeter in their smaller (R1 and R3) models.  This offer a wonderful experience.  You ought to be able to find the older RS 3 model in this range.  

Magnepan, Martin Logan or other electrostat/planar panels.  The only thing to note is these like power and depending on the speaker, amp matching can be interesting.  Magnepan is warm and like brighter SS amplification.  Martin Logan is cold and needs neutral to warm amplification.  

The ultimate speaker for this experience is MBL.  I doubt you will find one used in that price range.  

You definitely need to listen to at least one brand of omnidirectional loudspeaker, to discover if this is, generally speaking, the kind of effect that you are looking for.
