No wall treatments / sound proofing ... except the room is carpeted and a raised platform for the 2nd row seats.  The 2 tables on the left and right of the front row seats (red and black ones) are laptop tables

I'll try to grab some more pics of the room next time ...

No worries bro! nothing to feel sorry on tight budget ! You are absolutely fine to ask a question here.

From my point of view, you should be able to get an amp at around that price, maybe a little bit more on top, but bear in mind, that is just to buy an amp, you will need some budget to buy speakers, cables etc..  It depends on how you want your set up really.

If you can specify some details in terms of what sort of system would you like to have (stereo, 5.1 / 7.1 etc) , maybe some sifu would be able to give you some suggestions .

Cheers pal.
