My first Wilson Audio speaker. To be honest, I wasn't very impressed in the beginning. They were up against Totem Tribe Towers, which were great sounding speakers in a fantastic little package. The Tunetots actually sounded quite similar: neutral, but not harsh or sterile, with a little more upfront presentation, larger scale (perhaps because they are considerably taller on 26" stands than the TTTs), a little sharper, a little more density. In fact, I think the TTTs imaged a bit better. I was having a hard time justifying the nearly 2x price tag of the Wilson's... until I added a subwoofer.
The REL T-Zero Mk III didn't just fill in the bottom end, it really opened up the midrange and let the Tunetots bloom! Now I can't imagine a better sounding speaker for this application.
