XM Satellite Radio via a "SkyFi" tuner, using SilveryFirst sterling silver interconnects.
It is digital and sounds quite good (especially with tubes) but not quite to CD. But the programming is beyond belief.
Favorite stations (out of the 101 offered):
Luna 75 (Latin Jazz)
Café 45 (Sophisticated, funky eclectic rock, alt, acoustic stuff)
Frank's Place 73 (Great American Songbook - Frank, Ella, Billie H., Mel Tormé, etc.)
VOX 112 (vocal classical - all forms - chorale, opera, etc.)
Best of all, when I head to work, I pop off the bar-of-soap-sized tuner and pop it in the car. When I get to work, I pop it into the "boombox" cradle on my desk and pop on the headphones.
Life is good!
