Just out of curiosity, can you rank the SDA line in order of excellence. I just bought Studio 1C's used, and I think they sound FANTASTIC! I hear people talk about their 1B's, 1's, 2's, 2B's, SRS's, 1.2, 2.3's, etc. I saw the Polksda.com website, but it didn't have specs or reviews of them. I'd love to hear from those that have heard many SDA's and a ranking of them. I know it may be difficult since you may not hear all the speakers on the same gear, but I figure some may have. How do 1C's compare to 2B's? 1.2TL's? etc. I see people make some blanket statements about speakers, "The 1B is known to be... blah blah blah". Would love to be able to see the entire picture.
