What tuner would sound better

I am amazed how good my little MusicStreamer II sounds compared to my vintage Sansui 919 tuner

the Sansui is fuller and more nuanced with better imaging too but it does not hurt my ears to go back to the MusicStreamer

I know this is not a glowing review for the MusicStreamer but it has nice tone and can be enjoyable.

And of course the Sansui is no Day Sequerra

fwiw ymmv

"If I was to tell my boss something was impossible I would be looking for a another job. "

yikes!

I was just hoping to shed some light that digital is pretty good these days but I see you really need specific information. Of course even the Day Sequerra depends on the signal fed by the station so a difficult question indeed.

good luck
