Want to buy new HT setup, any help appreciated

Hi,

I would like to set up an HT and ready to spend upto $1000, I am looking at HTIB as well as expolring another possibilities.

Here is my current Music system

Jolida JD 100
Odyssey Tempest Pre
Odyssey Startos with Cap Upgrade
Paradigm ref studio 100 V2

I will not prefer to use these components for HT as in near future, I will be looking at upgrading speakers.

I am not sure whether any HTIB will be good enough for the
room of size 22 X 20 X 10.

If I want to go with Different receiver/ different Speakers and Diff sub, what are the option available ?

Thanks a lot,

Milind
