2.0 setup under 40K

[Trinath]

I'm planning to build a speaker setup. I'm new to audio world. At first, i thought of buying a 5.1 sound bar setup but listening to sound demo from nearby stores, i dropped that idea. After reading reviews, for my 150sq.ft room, it seems 2.0 setup is good. I don't know which one to pick. No one tells what's good company. Can anyone help me find a good pair. I'm open for preloved ones, but i don't have any big stores in my town to sound test them. So, i just have to buy from online. And most confusing part is amplifiers. Many reviewers said, if I don't pair with some high price amplifier, speakers gonna sound sh*t. Please help me find amplifier also that pair well with speakers. Thanks!
