I've heard both, although months apart and in a different room. I think they both sound terrific. My impression is that the Thiel is quicker with, perhaps, a bit more resolution. Also, I think the Vandy is slightly more coherent and musical. Tough call - I could live happily with either. I would have figured out how to pay for the 3As a long time ago if the WAF wasn't so low. I was ready to pull the trigger on the 2.4s last year but was set back with some unexpected expenses. . . I also know someone who has lived with both. Although he used to prefer the Thiels, he has recently concluded that they tend to overemphasize sibilance and now thinks Vandys are better overall. I have been enjoying my Thiel 1.6s for almost 5 years but have been wanting more bass. I've recently decide to try the new Vandy 2ce Sig II, which is supposed to be nearly identical to the 3A Sig from the midbass up, but in a smaller package.
