Doesn't get much simpler than my great sounding kitchen system.
21 year old Klipsch super efficient speakers with 2 10's and a horn.
40 year old (damnnn I'm ancient as I worked there then) Carver PM amp with clean 150 watts a side.
and finally........
Yes, a signal source of my Alexa pod with a headphone jack, feeding straight to the amp, which drives the speakers...............who says you need a $8000 pre-amp and welding cables for wires?
I don't care what fancy over-sampled front end signal processing and amps you run, it's only going to sound as good as the speakers.
