PSB Image B25. Very sensitive for its size with extraordinary dispersion and linearity.
You may think I'm nuts here, but maybe you should look into a pair of
Cerwin-Vega CLS-10 floorstanders. Although they're kind of a frat house speaker, some new designers at CV who have come out of audiophile companies (I think Boston Acoustics) have put better, more linear Scandinavian-sourced midrange and HF drivers in there for a fast and transparent midrange. They also will give you more oomph for your 35 wpc with 90dB sensitivity. The flagship model from this series, the CLS-215, has gotten favorable reviews in Absolute Sound and Soundstage. You can probably see them at Guitar Center.
