I am sure the music you would get from an "old fashion" source like a TV or a tuner would sound pretty good, isn't there some inexpensive computer you can find with internet connectivity. If not do what we always did find a tuner -which BTW are selling for close to nothing- and play a good station through your high end gear it will sound pretty good.
A little off the track of this thread. I was able to buy excellent digital Sansui Tuners for really next to nothing, models like the t-60. The more expensive ones were all analog but not tube like the TU-919, I own a TU 717 amongst others they sound great playing throughj modern gear.
