The Gallo CDT tweeter is very revealing. I would stay away from bright amplification and lean toward the warmer side. I have run Gallo ref II's on solidstate and tube amps. I have yet to try a hybrid which I think might be the best match.
On the Ref III I think you can run tubes on the top and solidstate on the woofer. This would obviously be a big step for newbie. However, I am running VTL 25 Watt tiny triodes with suprising results. The VTL IT85 might be an interesting match for the Ref III. This tube integrated has outputs to run additinal tube amp for bi-amping or solid state for subwoofer. Just an idea.
