This is by far my favorite Radio. A Delphi/XM Radio product, after several years of ownership, it remains on several hours a day at home while I enjoy many many channels, from Baseball to Classical Music to the BBC World Service, to World Cup Football, to NPR, to Old Time Radio, Drama, Jazz,and much more. The sound is great. I rarely have trouble picking up a clear signal. Delphi certainly knew how to make a boom box that gives great sound for those classical music channels (a real test).[[ASIN:B00008CLZS Delphi SA10001 XM SKYFi
