Thanks for your valuable suggestions people...

.. First of all I'd like clarify that I'm not a techie person in audio/video. I came to know about some terminology like avr, e.t.c only after visiting your forum. Is AVR is the only option since some of my friends says that some Home theatre systems without player is available which has co-axial input too? Moreover in my dvd player itself HDMI upscaling facility is provided. And My budget is only under 15K. :sad:
