It's upgrade time!
My short list is the two speakers listed above; unfortunately neither dealer here in Seattle has them in stock. The PSB dealer has offered to allow me to audition the S-Ones at home for a couple of weeks with the matching center speaker. I don't have a similar commitment from the Usher dealer yet.
Assuming that I can get the Usher dealer to do the same, does anyone have a recommendation of which one to try first? Ideally I won't have to try the second pair if all goes well.
