If you want a good sound stage then go for Floor standers. Also these will give better bass.
Mission 34 and 35 will fit in your budget. These can be had for anywhere between 20k and 30k depending on where you buy[Vijay sales in mumbai being cheapest]. The vocals and midrange are good in missions.
If you trying for bookshelf try auditioning Dali lektor 2 and Tannoy custom F1.
