what's about room correction?-Hypex Amp
-Topping DAC
-Stream through a computer
-Audiolense or Aucurate
All under $1500 and all near state of the art
This set up only lacks the ability to upgrade to a sub, which is possible but needs an additional DAC/amp or crossover/amp.
AVR is only bought when you need
1. Surround and the upmixing options that come with it.
2. Sound compression for loud sounds or the opposite increasing soft sounds during low volumes such as Audyssey's options.
3. Some type of room correction which is also offered with AVR's
If your listening to 2 channel music then I do not recommend an AVR, especially that this is going to be a secondary music only set up. It's like using a rally car on a race track.
I have an old AVR (x3400h) and a nVidia Shield. While my main use is movies and games, playing music is a breeze with casting from tidal or youtube
