Daniel,
There are lots of options out there for a good stereo system. Think different.
Why subs? Do you have to have sub-woofers? Have you checked out AVS Forum? Is this for a car? What kind of setup are thinking as far as listening environment/listening room?
Klipsch R-15PM are powered, which means, they don't need an amplifier/receiver. They accept a bunch of inputs, including connecting to your phone using Bluetooth.
There are so many options, oh my gosh...
for a while there, I had a pair of Dynaudio BM5A MK II, which are studio monitors that cost about $800 at the time.
I connected them to my audio interface, which in turn was connected to a blu-ray player, PC, TV, and other things.
I could also plug in my headphones to the audio interface, which was a Mackie Onyx 1640.
This setup is more for Pro Audio work.
The Klipsch speakers above are good content consumption speakers.
Why not a simple Yamaha or Denon receiver with a pair of good stereo non-powered speakers like ELAC or KEF (Credit: Wirecutter)
ELAC Debut 2.0 B6.2 for $300
or
KEF Q150 for $550
KEF Q350 for $650
Maybe you can find a new receiver on sale from 2016 or 2017...probably just as good as the 2018 models.
What is your budget?
