Hello Rohit!
I hope you had NOT made your choice by now. Dont take me wrong, cuz it takes a lot of auditioning from your end to zero in on the pair that YOU like the most. All of us can only suggest - its your hard earned money and what ever you buy, should sound sweet to you.
So just in case you have not made the purchase, I would any day suggest a fullrange floorstander compared to a pair of bookshelfs. NOW, I am risking the possibility of an outburst from the audiophile community for saying that. Your choice may be influenced by the size of your room, the type of music you listen too, and possibly the volume too. The same mid bass driver in a smaller enclosure is often less efficient and needs more power to run them well.
Very general statement here with exceptions to the rule but a larger floorstanding speaker genrally has a larger scale meaning full symphonic works,choral works etc. They make sound more believeable in it size and scale of the audio picture. I believe that a good pair of floorstanders can belt our full bodied music, they are not fuzzy about placement and most importantly will help you get away with the excess expenses associated with fancy stands or even a sub-woofer; if you are a purist.
Having said that, I would urge you to look into
a) Wharfedale Diamond 9.5
b) Monitor Audio Reference Series BR5
c) Kef iQ5
I believe all the above mentioned models should come within your budget and complement your amp. You did not mention your source(?!) If you are playing ur fav cds out of a 5K philips or sony, please, do yourself a favour and upgrade to atleast the entry level models from Cambridge Audio, Marantz and NAD. I heard the CA 640C v2 and Marantz CD6002 both give spectacular performances for the price and are highly regared as great value for money by the pros. Trust me you will not regret it!
In case, you are still inclined towards bookshelves, then dont think twice, go ahead with the suggestion of "particleman". I totally agree with
a) B&W 685
b) Epos M12.2
c) Monitor Audio RS1
All the best!!!
Note: I really appreciate if you could let us know what you finally purchase and how it sounds. Thanks!
