I'm Keeping it as simple as you can.
I'm playing around with a new setup. only 3 pieces.
Audio Source
Amp
Good Speakers
Starting in reverse:
Klipsch Speakers, very efficient. Clean sound with two 10's and a horn.
Carver Stereo Amp, 200 true watts per channel.
Your audio source, in my minimalistic form, an Alexa Dot with 3.5mm output jack.
It's my Kitchen system.
