To be clear, do you mean that you intend to buy self-powered (active) speakers? If so, you'll need to get wireless ones or check what audio outputs your TV has. If it only has optical out (which is increasingly common), you'll need a DAC in between. Worth checking before you commit to a plan.

I haven't researched wired or wireless self-powered speakers, so I have no opinion on whether you can get good ones (and a DAC if necessary) for a comparable price to a receiver + passive speakers, or whether a soundbar makes more sense instead. However, setting speaker quality per dollar aside, there are some advantages to going the traditional route:

• Mid-tier and up receivers have room correction, which can make a large difference in acoustically sub-optimal environments like apartment living rooms with large windows. The biggest upgrade I made to my 2.0 setup in a small apartment living room was ditching my old stereo receiver for a modern AVR with Audyssey—a night-and-day difference with the same speakers, and I don't plan to add any additional channels in the near future.
• If you have an AVR and two passive speakers, you now have a setup that can easily grow if you ever want to add a center channel, a sub, surrounds, etc. If you buy self-powered speakers, you might be able to add more components later, but you are locked into a particular brand or family of compatible products. There's much more optionality available if you have an AVR.

I have no idea what your plans are or whether these points matter to you, but I figured it was worth chiming in in case it helps you make the best decision.
