Harbeth vs Vandersteen vs Sonner

Thanks to all for your comments. I certainly intend to listen to them all and make my own decision based on my likes/dislikes. Always have. Since I originally intended to go with a 100 watt tube amp (Rogue Stereo 100) I guess my concern at the moment is whether or not that is enough power for the Treos. I hear that they are a bit power hungry. Could I hear from Treo owners as to how much power they are using with their Treo speakers and perhaps whether or not a tube or transistor amp is preferred?

Thanks especially to mr_m and gdnrbob for their first hand comments on power requirements for the Treo. I'm very please to hear that. And thanks to all who commented.

Thanks for asking. Here's what I did:
Kept my Well Tempered Table and Arm and installed a Sound-Smith Paua. Purchased an Aesthetix Pallene and Aesthetix Atlas Signature (used). Audioquest Robin Hood cables and McKenzie interconnects. And finally...tada...Vandersteen Treo CT's. Installed GIK acoustic panels as needed. Love, absolutely love the  system. Now....how can I improve it? Ha ha. I'll post some pics of my dedicated listening room on my profile. The room is also used for home theater. I replaced the Aerial 7b's with the Vandersteens but kept the Aerial sub, center and surrounds. Use the by-pass mode when watching movies. Oh, and a big thanks to John R and Samir at Audio Connection.
