"Antenna is no-go for me because I read internet radio has better overall sound."
Internet radio certainly will have more variety. "Better overall sound?" What website is making this declaration?
I have heard really good file based setups, but not internet broadcasts.
Mid level digital stream against high level tube FM tuner-REL, Marantz, Mac or SS...may be a different story?
Perhaps someone can chime in on SQ of mid/high level digital against the best FM tuners?
