That amp will not cope well with very hard to drive Vandersteen speakers. I would echo Soix's POV exactly. Those speakers need a bit more oomph.
Thoughts? - First Watt F8 / Vandersteen Treo's
Always have been interested in the Treo's after hearing these at a friends. I have run across a lightly used pair but it seems to me looking at the specs these are not a good fit with my First Watt F8. The F8 being a Class A puts out 25 W - 8ohms. The Vandersteen site shows a minimum of 40W into 8 ohms and sensitivity of 85 db. First glance tells me that this is likely not a solid combination. Thoughts?
