The best at this price range. I have bought it from store at 18k and the same day Sony customer services insured to install it. Sound frequency range is perfect, clarity is perfect and Base is more than I need. I listen it at -2db setting although I am a Base freak then also at this level only Base is more than I want.
Please try to avoid using extra external cables with the surround speakers as it decreases sound.
I am using it with my PS4, dth, TV output, mobile Bluetooth, 2 Tb HD ALL WORKS PERFECTLY.
