Could anyone give an idea, about which speakers is the best for my budget under USD 2,000? for second hand price/used goods.

Thank you.

Consider new Salk SongTowers which can be purchased internet direct including shipping for under USD 2000. I have them and they are spectacular, accurate and beautiful mid range. Custom built in the US. See several threads on avsforum and audiocircle.
Based on room size, low-power amplification, and budget, I can chime in with a recommendation for a pair of older Altec Model 19s, though they are quite large themselves. I have never heard Audiokinesis' speakers but I have great respect for the mfr's understanding of what makes speakers sound good, so I think that might be a good avenue to pursue as well.
