No, they don't compete with any of the speakers you mentioned. Most consumers who aren't well versed in music reproduction think Bose and Cerwin Vega are the top of the heap, but they don't have a point of reference. I'd consider a pair if I got the 901's for $100 or less and used 'em in a workshop system along with a vintage receiver. What equipment would you use with the 901's? Music preference, room? If you're considering a pair of Bose due to budget restrictions we can make recommendations for better speakers in the same price range.
