@thechordmaster as this is going to be your first build and, since you have been lurking around on the forum, lurk a bit more and go through this thread before getting into any OLX deal;

@SEANDSILVA 's posts. His words there have their worth in gold and must've been spoken in a drunken stupor.
Don't go for AVRs for a stereo setup. An AVR for 5K, you can bet your left nut there's some kind of phuckery afoot. Even if it turns out to be a functioning unit, then also we are talking about a product whose potential and performance is wasted as its not being used as intended by the manufacturer i.e. driving 2 channels instead of 5.
Wharfedale Speakers look good in the pictures but unless the seller can provide you a full function check through video or over video call or you can personally inspect them, don't be tempted by them. There are loads of ways a speaker can turn out to be kaput whilst looking clean and pristine.
Moreover, most of Wharfedale speakers have either a laid back or warm signature. Pairing them with an amplifier such as Norge or NAD would be a basshead's dream but a nightmare for almost everyone else. So when working with a small budget, your options are limited thus you have to prioritize your spending.
I also listen to music from 80s and A R Rahman and whilst I haven't auditioned Mission speakers personally, the respect they command makes them a safe bet for anyone getting their feet wet in audiophile game.
Norge amp and LX2, Pioneer amp and LX2, both are good starting points in a budget of 25-30K. To cut costs, you can take ChiFi route and look at D502 and Dayton Audio stuff.
Other route, totally unexplored in this thread, is going for pair of active bookshelf speakers, where in 15-20K range, there are some really good options.
At the end of the day, it's about you. What you want to listen and how and for that how much can you spend?
P.S- Look at this
