There was a guy who was powering his Talon Khorus speakers with the Bruce Moore 70/70 (70 wpc tube amp) and felt it bettered some of the high powered SS amps he had tried. The Ravens being a 2 way design and rated at 90 db are easy to drive and the sound will change if you are using a tube or SS amp. SS amps will generally provide more dynamics, and better control of the bass and the tubes add a 3D soundstage and more real range sonics. The Ravens are a very clear, dynamic and fast sounding speaker with a huge center stage image (depends on how much toe in you like). The bass is so tight and fast and if you are using the large spikes you should not notice any of the gerneral short falls that a tube amp can add to bass response versus SS. The bybee filters add even more refinement to the bass and high frequencies allowing the music to flow without any smearing of notes in all frequency ranges.
Happy Listening.
